PGOPHER <Prev Next>


The current version of PGOPHER is the product of many years research in the general area of spectroscopy. During that time my work has mainly been funded by the Engineering and Physical Sciences Research Council (EPSRC) and (in the early stages) by The Royal Society. I should also acknowledge the input of colleagues in Bristol and around the world for assistance in testing, finding bugs and making suggestions for improvements to the programs. There are too many to name individually on the whole, though I should mention Nicky Elliott who helped in the preparation of first version of this documentation, and Brant Billinghurst of the Canadian Light Source who encouraged me to work on the spectra that led to the development of the process described in Automatic Fitting of the nu5 band of cis 1,2-Dichloroethene.

Some specific mentions for recent additions:
The spectra of N2O and cis- and trans- 1,2-Dichlorothene used as examples in the Walk-through of Simulating and Fitting a Simple Spectrum and Automatic Fitting documentation were recorded at the Canadian Light Source with Brant Billinghurst. The Canadian Light Source is supported by the Canada Foundation for Innovation, Natural Sciences and Engineering Research Council of Canada, the University of Saskatchewan, the Government of Saskatchewan, Western Economic Diversification Canada, the National Research Council Canada, and the Canadian Institutes of Health Research.

Other software used

All versions of PGOPHER make use of the LAPACK library for matrix diagonalisation and selected other matrix operations, as described in E Anderson, Z Bai, C Bischof, S Blackford, J Demmel, J Dongarra, J Du Croz, A Greenbaum, S Hammarling, A McKenney and D Sorensen, LAPACK users guide, 3rd Ed., Society for Industrial and Applied Mathematics, Philadelphia, 1999.

In addition the following components are used are used in some Windows versions of the program, or have been used as a base for some code:
The files as originally downloaded are included in the wutils/required directory in the source code archives.
