The physics of rotational tunneling: hole-burning spectroscopy of methyl groups

Methyl groups are most outstanding quantum systems due to their inherent symmetry
 properties which cannot be destroyed by any kind of lattice disorder. We show how optical
 hole-burning techniques can be employed to measure rotational tunneling relaxation processes.

description Methyl groups are most outstanding quantum systems due to their inherent symmetry
 properties which cannot be destroyed by any kind of lattice disorder. We show how optical
 hole-burning techniques can be employed to measure rotational tunneling relaxation processes.
 Since the tunneling parameters are extremely sensitive to changes in the host lattice, there is a rich
 variety of relaxation phenomena that can be observed. Hole-burning techniques have the
 capability of measuring not only extremely slow processes with high precision but also rather fast
 processes. We exploit this possibility to show that the relaxation times at 2 K change by 14 orders
 of magnitude if the permutation symmetry of the methyl group is destroyed by asymmetric
 deuterium substitution.
