“…Power switching is achieved with fast pin-diode switches, capable of generating pulse durations of less than 10 ns. The emission signals are rather weak, ranging from 10 −12 W for the strongest transitions to less than 10 −20 W at the detection limit (Gripp et al 1995). For weakly polar species, quite high pulse powers beyond the W range are needed to create an "effective π /2-pulse".…”

Microwavemolecular spectroscopy is progressing impressively. In part, profiting from recent experimental developments that combine jet‐expansion sources with elaborate means for preparation of new chemical systems, advances in spectroscopic instrumentation — namely, the rise of very sensitive and high‐resolution time‐domain techniques — are even more significant. Precise structural studies have always been a strength of rotational spectroscopy; now problems arising from convoluted intramolecular dynamics, such as conformational, tautomeric equilibria, and other large amplitude motions, as well as intermolecular vibrational energy redistribution and isomerization, can be targeted with the unrivaled precision of rotational investigations. Numerous interesting chemical systems like molecules with multiple concurrent internal motions, larger complexes, aggregates, biomolecules, and transient species were characterized recently — positioning microwave spectroscopy today as a prime method for the investigation of multidimensional flexible systems. Rotational studies elucidate an extensive range of intermolecular interactions, ranging from hydrogen bonding and van der Waals interaction to the unusual effects observed in quantum solvation. The development of microwave pulsed excitation multiresonance techniques and the advent of instantaneous broadband‐coverage microwave spectroscopy are impressively boosting the capabilities of rotational spectroscopy to quite routinely disentangle the unique spectral signatures that encode the structure and dynamics of hitherto pathological molecular cases. The versatile capabilities of microwave coherence spectroscopy are outlined in the treatment of time‐dependent interaction of rotating molecules with radiation.

“…The file called "627.obs" contains data (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) for the 16 O 12 C 17 O species and the other file "628.obs" contains data (9,(12)(13)(14)(15)(16)(17)(19)(20)(21)(22)(23)(24)(25)(26) for the 16 O 12 C 18 O one. The numbers of lines in the 627.obs and 628.obs datafiles are 1957 and 7200, respectively.…”

“…About 1800 measured line positions belonging to 30 bands were collected from the literature [11,26,28,[35][36][37][38][39][40][41] and used to derive 45 parameters of a reduced effective Hamiltonian. The dimensionless weighted standard deviation, χ, of this fit was 1.63 and the RMS deviation was 0.00129 cm À 1 .…”
