Infrared spectroscopy of chemically doped solid parahydrogen

This review article presents an overview of recent infrared spectroscopic studies of chemical species trapped in solid parahydrogen at liquid helium temperatures. An overriding theme that emerges from this work is that, even at liquid helium temperatures, chemically doped solid parahydrogen is dynamic with a variety of quantum mechanical and energy transfer processes that occur, such as orthohydrogen quantum diffusion, hydrogen nuclear spin conversion, and, in radical doped parahydrogen solids, chemical reactions can occur. To illustrate these dynamical phenomena we examine (1) clustering of orthohydrogen to dopant molecules, (2) solid parahydrogen infrared absorptions induced or perturbed by the presence of the dopant, and (3) chemical reactions initiated by infrared absorptions of the parahydrogen solid.
