Aims |
|
The aim of this module is to instruct students in the practice of taking physical measurements, the critical analysis and evaluation of experimental data, the application of measurements to the study of chemical phenomena and the dissemination of results. |
Learning Outcomes |
|
By the end of the module, students should be able to 1. take physical measurements of varying complexity using a wide range of experimental techniques; 2. assess the risks involved in chemical lab work and handle chemical materials in a safe manner; 3. choose appropriate methods for the analysis of data; 4. analyse experimental data using graphs, spreadsheets and linear regression; 5. assess the accuracy and significance of experimental results; 6. apply the results of physical measurement to the interpretation of chemical phenomena; 7. combine units and perform a dimensional analysis; 8. have experience of the application of spectroscopic techniques (UV, IR, NMR and mass spectrometry) in the characterization of organometallic and inorganic compounds; 9. organise and plan their time effectively. |
Syllabus |

The experiments comprise a series of workshops and experiments from Physical Chemistry and Inorganic Chemistry:
The first two workshops are designed to teach generic skills needed for the analysis of experimental results (Data and error analysis, Dimensional analysis). These are followed by a series of spectroscopic workshops. Each workshop will begin with a short lecture to introduce the topics covered. Students will be introduced to spin 1/2 NMR active nuclei other than 1H and will then work through problem sheets under the guidance of the demonstrators. The following material will be covered Introduc tion to the physical basis of NMR. Quantum numbers, energy levels, magnetic equivalence, chemical shifts, scalar couplings. Revision of CHEM 126 material. The use of mass spectra, infrared spectra, elemental analyses and multinuclear NMR spectra in the determination of the structure of inorganic and organometallic complexes. Scalar coupling (J values) in NMR and its use in the determination of stereochemistry and conformational analysis The workshops will be assessed by a combnation of continuously assessed material and a class test. |
Teaching and Learning Strategies |
|
This is a laboratory based module in which students practise a range of measurement techniques appropriate for the investigation of a wide range of chemical phenomena spanning thermodynamics, kinetics, spectroscopy, electrochemistry, surface science and transition metal chemistry. Students perform experiments with minimum supervision (although staff and postgraduate demonstrators are at hand to answer questions and provide guidance if necessary) and are responsible for planning and timetabling their experiments themselves. Each experiment is allocated a number of points based on its length and complexity, and students are required to complete experiments corresponding to a minimum number of points, although more experiments may be undertaken. Each experiment must be analysed using appropriate techniques and written up in a laboratory report which is presented to a demonstrator for marking before the next experiment is allocated. Marks are al located for the quality |
