โœฆ Synopsis


It is shown that if the absorption and luminescence spectra are normalized to the integrals of tJu and IJu3, respectively, the intersection point will generally correspond to the difference of the free energy of the system in the ground and in the excited states. Knowing the free-energy difference, one can find the change in other thermodynamic characteristics of the system due to electronic excitation.

The clectran-impact ener&y-loss spectrum of ketene has been measured at impact energics of 30 CV end 50 cV, and SGI~tering angles varying from 5" to 80". Transitions hzvc been observed at 3.7.5.3, and 5.86 cV. These values are in excellent agreement with recent high quality ab initio calculations. T
