Overview

Module aims and purpose

This module introduces a range of modern analytical chemistry techniques relevant to the molecular sciences. Mastering these techniques at a comprehensive level offered by the module content adds significantly to the tools expected, and requested, from a capable chemist with academic education. The scheduled lectures and workshops will be delivered by renowned field specialists in an attractive and interactive fashion. 

Electrophoretic techniques(complementary with chromatographic techniques, e.g., HPLC) are widely used in medical diagnostic laboratories and in identification and authentication of animal foods as well as plant foods, for example brands of different foodstuffs that have protected geographical status. 

Mass spectrometrydetects molecules without specialized molecule-specific reagents. This makes it an unbeatable tool for rapid and tailored problem solving. The types of analyses performed are diverse and can include activities ranging from intact mass measurements of small molecules to proteins with a molecular weight over 100kD. 

Multi-nuclear magnetic resonanceandElectron paramagnetic resonanceare important universal spectroscopic techniques used widely in molecular and materials chemistry for descriptive and analytical purposes, encompassing all the periodic table of elements, specifically a range of suited magnetically active naturally occurring isotopes. 

Sophisticatedvoltammetry with ion-selective electrodesandanodic/cathodic stripping voltammetrybelong to the most sensitive and selective analytical tools for everyday applications in many areas of human activities. Their role especially in targeted environmental and biomedical analysis is indispensable. 

Scanning probe microscopyis a branch of microscopy encompassing several techniques that form images of surfaces using a physical probe that scans the specimen. It was founded with the invention of the scanning tunnelling microscope, an instrument for imaging surfaces at the atomic level. It is extremely important for the areas of nanotechnology and biosensors, offering the advantage of high lateral resolution.

Module learning outcomes

By the end of the module, it is expected that students will be able to: 

  1. Demonstrate thorough understanding of the advanced analytical techniques covered in the module and appreciate how such techniques can be used independently and in conjunction with other techniques to elucidate molecular structure and identity; 
  2. Analyse, interpret and present data from a range of analytical techniques in an appropriate format; 
  3. Express the role of analytical chemistry in science and the position of the taught techniques; 
  4. Demonstrate ability to solve complex problems and a systematic approach to tasks.

Use of chemical shift and hyperfine coupling information to solve molecular structures and describe bonding properties of organic, inorganic and coordination compounds. Quadrupolar effect and its origin. Isotopic labelling and ways to distinguish between NMR-active isotopes of the same element. 

Electron Paramagnetic Resonance Spectroscopy (4 lectures + 1 workshop + 1 revision workshop) 

EPR spectroscopy in studying paramagnetic molecules. Instrumentation and comparison with NMR spectroscopy. Analysis of EPR spectra - g values, hyperfine splitting and intensity patterns. Difference in EPR signals of active isotopes of the same element. Isotropic and anisotropic EPR spectra. Spin trapping of short-lived radicals. 

Scanning Probe Microscopy (3 lectures + 1 workshop) 
Introduction to scanned probe microscopy, resolution and imaging mechanisms. Scanning tunnelling microscopy: image formation in UHV environments, imaging chemical reactions, atomic manipulation and discussion of limits to applications. Atomic force microscopy; cantilever dynamics, contact and non-contact imaging modes, force spectroscopy, chemical force and molecular pulling. Extensions to imaging in liquid environments consideration of cantilever dynamics and new methods and apparatus.

Structure

Teaching and learning methods

Module content will be delivered through in-person blocks of 3-6 lectures on a given topic. Each of the six module topics will be accompanied by one formative workshop (compulsory) in which students will apply the theory, principles and concepts of the different analytical methods to solve relevant problems. In addition, a problem-based tutorial sheet, covering Scanning Probe Microscopy in the course, will be issued at the end of the first half of the semester. This tutorial will be summative. Students will submit written answers, which will be marked. The mark will contribute to the overall module mark. Feedback on the marked work will be provided through a set exercise (compulsory). There will be a total of 5 hours of revision workshops towards the end of the semester in preparation for the written examination that will exclude Scanning Probe Microscopy. 

Study hours

At least 34 hours of scheduled teaching and learning activities will be delivered in person, with the remaining hours for scheduled and self-scheduled teaching and learning activities delivered either in person or online. You will receive further details about how these hours will be delivered before the start of the module.

Penalties for late submission of summative assessment

The Support Centres will apply the following penalties for work submitted late:

Assessments with numerical marks

  • where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of three working days;
  • the mark awarded due to the imposition of the penalty shall not fall below the threshold pass mark, namely 40% in the case of modules at Levels 4-6 (i.e. undergraduate modules for Parts 1-3) and 50% in the case of Level 7 modules offered as part of an Integrated Masters or taught postgraduate degree programme;
  • where the piece of work is awarded a mark below the threshold pass mark prior to any penalty being imposed, and is submitted up to three working days after the original deadline (or any formally agreed extension to the deadline), no penalty shall be imposed;
  • where the piece of work is submitted more than three working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

Assessments marked Pass/Fail

  • where the piece of work is submitted within three working days of the deadline (or any formally agreed extension of the deadline): no penalty will be applied;
  • where the piece of work is submitted more than three working days after the original deadline (or any formally agreed extension of the deadline): a grade of Fail will be awarded.

The University policy statement on penalties for late submission can be found at: https://www.reading.ac.uk/cqsd/-/media/project/functions/cqsd/documents/qap/penaltiesforlatesubmission.pdf

You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.
