The literature on the high-resolution spectroscopic investigation of molecular complexes containing small polyatomic species excited in their vibrational overtones is reviewed. They turn out to be complexes containing acetylene, ammonia and water, ma

We have investigated the N2O–HDO molecular complex using ab initio calculations at the CCSD(T)-F12a/aug-cc-pVTZ level of theory and using cavity ring-down spectroscopy to probe an HDO/N2O/Ar supersonic jet around 1.58 μm. A single a-type vibration

A high-resolution spectrum of the acetylene–water complex has been recorded in the overtone range. Two bands of C2H2–D2O were analysed, corresponding to the overtone excitations of either the acetylene or the water units. The vibrational shifts a

A preliminary analysis of the 2CH excitation band in C2H2–N2O in the 1.5 mm range (K. Didriche, C. Lauzin, P. Macko, M. Herman and W.J. Lafferty, Chem. Phys. Letters 469, 35 (2009).), only considering 117 low J-, and Ka- vibration-rotation lines, i

CW-cavity ring down spectroscopy was used to record the spectrum of 12C 2H 2-N 2 in a free jet expansion around the 2CH acetylene band. Twenty lines were assigned thanks to combination differences, which were combined with literature values leading t

The first observation in the near infrared of the (12)C(2)H(2)-Kr van der Waals complex is reported, leading to the determination of rotational constants and the prediction of the 1 0 1 (J'K(a)'K(c)') ← 0 0 0 (J''K(a)''K(c)'') microwave transition

Ethylene (ethene, H2C=CH2) is a naturally occurring compound in ambient air that affects atmospheric chemistry and global climate. The C2H4 spectrum is available in databases only for the 1000 and 3000 cm−1 ranges. In this work, the ethylene absorp

A supersonic expansion containing acetylene seeded into Ar and produced from a circular nozzle is investigated using CW/cavity ring down spectroscopy, in the 1.5 μm range. The results, also involving experiments with pure acetylene and acetylene-He
