Coherent photodissociation reactions: Observation by a novel picosecond polarization technique

In this communication, we wish to report on a novel picosecond polarization method for measuring the degree of rotational coherence that is preserved in photodissociation reactions. The systems studied here are jet-cooled van der Waals molecules; stilbene [4-6] bound [5] to He or Ne with a 1:1 composition.[7

President\u27s Notes: Challenge!

For the past 9 years, the Naval War College and The George Washington University have joined together in a cooperative graduate program leading to masters of science degrees in international affairs awarded by the university

President\u27s Notes: Challenge!

Since its establishment in 1884, the U.S. Naval War College has provided advanced education in the science of naval warfare and related subjects to hundreds of senior naval officers, enhancing their professional competence for higher command responsibilities

Challenge

The challenge implicit in adapting U.S. defense posture to the financial and political realities behind the Nixon Doctrine is being met throughout the Armed Forces in a several ways. A program at the Naval War College, which has contributed extensively in the past to free world cooperation and should be responsible for even greater contributions in the future, is the Naval Command College

President\u27s Notes: Challenge!

In early November 1971, some 91 senior naval officers representing 42 nations assembled at the Naval War College for the second International Seapower Symposium

Picosecond real-time studies of mode-specific vibrational predissociation

The vibrational predissociation of several van der Waals complexes of t-stilbene has been studied by directly measuring, in real time, the fluorescence intensity from the initial reactant state and from the individual product states formed in the dissociation process after exciting single vibrational levels of the complex. With the aid of a kinetic model involving sequential processes, the individual rates for intramolecular vibrational redistribution and vibrational predissociation in the overall dissociation process are resolved and distinguished in several cases. In the stilbene–He complex, the dissociation is significantly faster from low energy out-of-plane modes than it is from a higher energy in-plane mode
