Laser Spectroscopy and PGOPHER

An important technique, both in our work and Chemistry in general, is the use of spectroscopy to probe molecules.  In the Bristol group, spectroscopy finds applications in determination of molecular structure, identification of excited electronic states, study of reaction products, and as a probe of atmospheric or plasma chemistry.  One of the products of this work is the PGOPHER program, a tool that has been developed to interpret different types of spectra as part of many years of research. This program has been made available to the community, and is now in use by many research groups throughout the world.

PGOPHER program

PGOPHER is a program for simulation and analysis of rotational, vibrational and electronic spectra of molecules and radicals.

Trace Gas Sensing

Techniques based on cavity enhanced absorption spectroscopy in the infra-red region are used to monitor trace atmospheric constituents.
