Abstract

For IRMPA/D (Infrared Multi-photon Absorption / Dissociation ) studies, we measured IR fluorescence emitted from vibrationally excited DF{sup *} or HF{sup *} produced in IRMPD of CDF{sup 3}/CHF{sup 3} using ir monochromator and InSb ir detector. We could detect the ir fluorescence of HF from the sample mixture CDF{sup 3}/CHF{sup 3} to which the CDF{sup 3} was selectively irradiated. This means that the molecular selective excitation of CDF{sup 3} in CDF{sup 3}/CHF{sup 3} mixture did not give molecular selective dissociation of CDF{sup 3} because of the fast intermolecular vibrational energy transfer from the excited state CDF{sup 3} to the ground state CHF{sup 3}. This technique will play important role for measuring isotope selectivity in IRMPD of CDF{sup 3}/CHF{sup 3}. We developed data analysis technique for the laser fluorometer to improve analytical speed and accuracy. We calculated a fluorescence intensity at time zero using two values obtained by integration of two intervals on time-resolved fluorescence signal. Applying this method, we could eliminate any interference effects from quenching elements or temperature fluctuations of samples, effectively. The applications of the instrument were broadened to the analyses of rare-earth elements and the trace analyses of Sm, Eu, Tb and Dy were successfully performed. To  More>>

The applications of the instrument were broadened to the analyses of rare-earth elements and the trace analyses of Sm, Eu, Tb and Dy were successfully performed. To improve resolution of the hologram, a bleaching method of silver halide emulsion hologram was investigated. The optimum condition for making transmission phase hologram of the silver halide photographic plate was also studied. The effects of the developer, the bleaching solution and the drying process were experimentally measured. The new recording geometry of the reflection hologram with high resolution and high efficiency was investigated theoretically and experimentally. And we compared this new method with conventional one. (Author).}
