Spectra of the D2O dimer in the O-D fundamental stretch region: the acceptor symmetric stretch fundamental and new combination bands

A. J. Barclay, A. R. W. McKellar, N. Moazzen-Ahmadi

The O-D stretch fundamental region of the deuterated water dimer, (D2O)2, is further studied using a pulsed supersonic slit jet and a tunable optical parametric oscillator infrared…

Infrared spectra of (CO)-Rg trimers, Rg = Ne, Ar, Kr, and Xe

A. J. Barclay, A. R. W. McKellar, N. Moazzen-Ahmadi

High resolution spectra of (CO)-Rg trimers (Rg = Ne, Ar, Kr, and Xe) in the region of the CO2 nu3 fundamental (~2350 cm) are reported, using a tunable OPO laser sour…

Observing the completion of the first solvation shell of carbon dioxide in argon from rotationally resolved spectra

A. J. Barclay, A. R. W. McKellar, N. Moazzen-Ahmadi

Widespread interest in weakly bound molecular clusters of medium size (5-50 molecules) is motivated by their complicated energy landscapes, which lead to hundreds or thousands of d…

Exploring the next step in micro-solvation of CO in water: Infrared spectra and structural calculations of (H2O)4- CO and (D2O)4- CO

A. J. Barclay, A. Pietropolli Charmet, A. R. W. McKellar +1

We extend studies of micro-solvation of carbon monoxide by a combination of high-resolution IR spectroscopy and ab initio calculations. Spectra of the (H2O)4-CO and (D2O)4-CO penta…
