Book Description
This volume contains eight invited papers and seventy-three contributed papers presented at the Fourth International Symposium on Gas Flow and Chemical Lasers. which was held in Stresa. Italy. from September 13 to 17. 1984. The purpose of the Symposium was to record and discuss current research developments and applications related to high power lasers. Papers were solicited from the entire spectrum of activities, includ ing basic physics, aerothermodynamics, new laser media, laser design, diagnostic techniques, laser propagation. interaction phenom ena, applications. The Symposium was an opportunity for scientists and engineers representing all these disciplines to come together to report their recent work, to exchange ideas and to provide an up-to-date account of international progress in these fields. The contributed papers were reviewed by the members of the Scientific Advisory CoEmittee. who also took responsibility for formulating the program of invited lectures. As editor I wish to express my appreciation and my gratitude to people and organizations that made this Symposium a success: the Members of the Scientific Advisory Committee, the Members of the Local Organizing Committee, the Sponsors and the Symposium Secretary. A grateful acknowledgement is expressed to Dr. M. Sandra Oggiano for assistance in the organization of the Symposium and publication of these proceedings.
Rotational Energy Transfer in Highly Vibrationally Excited Hydrogen Fluoride and Deuterium Fluoride

Book Description
Overtone vibration-laser double resonance measurements have provided new data on vibrational and rotational relaxation in HF(v=2). These experiments determine the magnitudes of the total vibrational relaxation rate constants for HF (v=1 and 2) as well as their temperature dependences. Detailed analysis yields the variation of the branching between competing V-V and V-TR pathways. Rotational relaxation data come from these measurements as well. The temporal evolution of individual rotational states observed in the double resonance studies provides level-to-level energy transfer rate constants when analyzed using an iterative fitting scheme which incorporates scaling relations among the rate constants. Originator supplied keywords include: Energy transfer, Rotational relaxation, Laser, Hydrogen, Fluoride, Deuterium fluoride.

Book Description
Combining the techniques of direct excitation of overtone vibrations and time resolved spectroscopic detection permits detailed measurements of the vibrational and rotational relaxation of highly vibrationally excited molecules. Using this technique, we have measured vibrational and rotational relaxation in HF(v = 3,4,5) between 300 K and 650 K and have compared these results to various theoretical calculations. Using laser double resonance to probe individual rotational states, we find phenomenological rotational relaxation rate constants which decrease montonically with rotational energy change in the vibrationally excited molecule, and we have directly measured the vibrational relaxation rate constants for v = 1 and v = 2 as well as made a preliminary estimate of the (surprisingly small) fraction of the relaxation which goes by vibration-to-vibration energy transfer.
