Outline of lecture

Modern process industries are increasingly focussed on advanced product engineering including foods, pharmaceuticals, personal care products, advanced materials, and other formulated products. An integral component of product engineering is the ability to describe the physical chemical attributes of the final product.

This course is designed to provide students with current knowledge and experience in vibrational spectroscopic techniques (Infrared and Raman) for product and process characterization.

Following completion of this course the students will be able to recognise the most relevant spectroscopic technique of choice to analyse a product (including its limitations and benefits). At the end of the course the student should be able to demonstrate knowledge of fundamentals and applications of current spectroscopic methods for materials characterization. Students will also be familiar with the broad areas of applicability of studies spectroscopic methods. The students will also be able to apply the skills learned in the demonstration exercise during the first lecture to the real-world products.

Purpose of lecture

For understanding of vibrational spectroscopy (Infrared and Raman), principles of spectroscopy are introduced first, based on the fundamental concepts of physical chemistry. Then the applications of vibrational spectroscopy to chemical products and processing, such as in the pharmaceutical industry, are discussed. Recent advances in instrumentation and measuring techniques are introduced.

Comments from lecturer

First lecture on Wednesday 8/04/2015 will include demonstration of measurements of infrared spectra of selected samples. A small FTIR spectrometer will be available during the lecture to demonstrate that spectra may be measured quickly and their interpretation can be achieve.

Slides of each lecture will be provided on OCW in advance of each lecture as pdf files.
