Abstract
The first overtone vibration-rotation transition of parahydrogen in a crystal containing a residual amount of orthohydrogen has been detecte d using high resolution laser spectroscopy. The observed spectrum show s several splittings due to the anistropic crystal field interactions. The crystal field splitting of a single J=1 orthohydrogen molecule in solid parahydrogen at liquid He temperatures is found to be 0.0070cm( -1) (0.0108 K).
