CHY2401 : Structural Chemistry

Semester 1 Credit Value: 20
ECTS Credits: 10.0


To introduce the principles of NMR spectroscopy and to familiarise students with the analysis of the NMR spectra of some organic and inorganic compounds; to explain the principles of X-ray diffraction by single crystals and the application of these principles in practical structure determination; to provide students with an appreciation and understanding of all aspects of modern mass spectrometry, building on their knowledge of traditional electron impact mass spectrometry; to provide the necessary background for the interpretation of the vibrational spectra of inorganic and organic molecules

Teaching Rationale And Relationship

This course covers the principal methods of structural determination used in modern chemistry.
The basis of the course is the lectures, but these are strongly reinforced by the closely integrated practical work which gives the students valuable personal experience of the most important techniques and how they can be applied in real life situations. The practical also provide a means of continuous assessment, and the tutorials are especially aimed at giving more theoretical backup

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The dry-lab practical assessed work will permit the student to practise and consolidate the lecture material and also allow the academic subject tutor to monitor progress towards the learning outcomes.

The examination will assess the student's knowledge and understanding of the basic principles of all areas of spectroscopy.

Study Abroad students may request to take their exam before the semester 1 exam period, in which case the format of the paper may differ from that shown in the MOF. Study Abroad students should contact the school to discuss this.
