Vibrational predissociation in the hydrogen fluoride dimer

摘要

A color center IR laser was used to excite the protonhyphen;accepting monomer of a HF dimer in a molecular beam. The maximum excess linewidth arising from vibrational predissociation was 10 MHz, indicating a vibrational predissociation lifetime of ge;30 ns. The maximum lifetime was estimated to be 300 ns from intensity considerations.
