Vibrational-Excitation-Induced and Spontaneous Conformational Changes in Solid Para-H2—Diminished Matrix Effects

Both vibrational-excitation-induced (by (N)IR laser) and spontaneous H atom tunneling) conformational changes are often investigated by matrix-isolation spectroscopy. It is well known that rigid hosts, such as solid noble gases, N2, or normal-H2, can largely affect both the quantum efficiency of photon-induced process tunneling rate. In present study, formic acetic acids, glycine, were in a soft host, para-H2. shown rates para-H2 orders magnitude larger than those hosts. Furthermore, our results also suggest efficiencies some (N)IR-light-induced matrices. These open door for applications host studies help understand details these complex processes.
