Abstract
A method is presented by which the effects of pressure on the absorption and emission spectra of a luminescent center can be used to provide the parameters necessary to construct a configurational coordinate diagram of the center. Pressure shifts of the 2470‐Å absorption and 3050‐Å emission bands of KCl:Tl have been measured and are used to calculate the parameters for the appropriate configurational coordinate diagram; the results are in good agreement with those obtained from purely theoretical considerations. Values for bandwidth and compressibility are also calculated and are found to agree with experimental observation.Keywords
