Abstract
Energy decay rate of the first vibrational excited state for solid parahydr ogen is measured from 4.8 K to 12 K. Measurements are carried out using the transient optothermal lensing spectroscopy with the vibrational excitation s via the stimulated Raman scattering. The decay rate is measured to be 2.3 x10(4) s(-1) at 4.8 K, and it increases to 6.1x10(4) s(-1) by raising the t emperature to 12 K. (C) 2001 American Institute of Physics.
