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 presentation of results.
Learning outcomes 
A. Take physical measurements of varying complexity using a wide range of experimental techniques (. experience of the application of spectroscopic techniques (UV, IR, NMR and mass spectrometry) in the characterization of organometallic and inorganic compounds).

B. Assess the risks involved in chemical lab work and handle chemical materials in a safe manner.

C. Analyse experimental data using graphs, spreadsheets and linear regression; choose appropriate methods for the analysis of data; assess the accuracy and significance of experimental results; combine units and perform a dimensional analysis.

D. Apply the results of physical measurement to the interpretation of chemical phenomena.

E. Organise and plan their time effectively.
Method of teaching and learning 
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.
Each experiment must be analysed using appropriate techniques and written up in a laboratory report.
Syllabus 
The experiments comprise a series of workshops and experiments from
Physical Chemistry and Inorganic Chemistry:
- Kinetics of the acid-catalysed hydrolysis of ethyl ethanoate
- Critical micelle concentration
- Boiling point - composition diagram
- The dipole moment of dibenzoyl
- Iodine absorption spectrum
- Redox potential of the iron system
- The dissociation of ethanoic acid by conductance
- Potentiometirc titration
- Reaction isotherm
- Fluorescence of Rhodamine B and its quenching by iodide ions
- Gas-liquid chromatography
- The enthalpy of neutralisation
- Bomb calorimetry
- The association of uranyl and thiocynanate ions
- The reaction of crystal violet with hydroxide ions
- Thermodynamics of ethanoic acid dimerisation
- The characterisation of reaction intermediates by NMR Spectroscopy
- Job's method
- Preparation & thermochromic transition of diethylammonium tetrachlorocuprate(II)
- Conductivity of transition metal complexes
- Magnetic susceptibility of nickel complexes
- UV-vis spectra of transition metal ions

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:
- Introduction 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
