Quantum beat spectroscopy in chemistry

“…Details of other recent work on Zeeman quantum beats may be found elsewhere. [17][18][19] Stark quantum beats are measured in a similar manner, with an external electric field being applied instead of a magnetic field. However for an isolated state, the Stark shift is quadratic in field, in contrast to the linear low field Zeeman effect.…”

“…Examples of other recent work on hyperfine quantum beats may be found elsewhere. 18,19,24,25 In addition, it is also possible to study the effect of external fields on nuclear hyperfine structure. The majority of studies have used external magnetic fields and an example recorded for the V system of 13 CS 2 is shown in Fig.…”

Transient Laser Frequency Modulation Spectroscopy

“…We suggested the strong electrostatic anisotropy in the exit channel as a possible explanation within the context of ground-state dissociation (57). The photophysics and nonradiative coupling of the bright state to the dissociative continuum is complex, however, and a role for triplet surfaces cannot be ruled out (76,77). It is almost certainly an oversimplification to consider the optical and nonradiative processes as merely a convenient way to prepare ground state NCCN molecules with a specific energy at time zero.…”
