Abstract
Solid para-H2 doped with CH3F at 1.8 K is studied in the n3 region (∼1040 cm 1) using a quantum cascade laser source. Residual ortho-H2 gives rise to distinct spectral features due to CH 3F(ortho- H 2)N clusters with N = 0, 1, 2, etc. The laser power (∼30 mW) is sufficient to significantly affect the sample, enabling novel photochromism experiments to be performed on a solid para-H 2 matrix-isolated sample. It is found that population can be reversibly transferred between the N = 1 line and satellite features close to the N = 0 line. © 2011 the Owner Societies.
