✦ Synopsis

State-selective detection of molecular hydr~en by VUV laser-induced fiuorescence has been achieved at excitation wavelengths greater than the bthium ftuoride cut-off, using xenon as the non-linear medrum-With this approach sensitivities of 010' per cm3 per quantum state have been achieved under cell conditions. This method provides a simple approach to monitoring the vibrational state distribution of hydrogen and its isotopes.
