Rotational spectra and structures of small clusters: Ar3-HF and Ar3-DF

Structural dependence of hydrogen fluoride vibrational red shifts in argon-hydrogen fluoride (ArnHF, n = 1-4), via high-resolution slit jet infrared spectroscopy

“…ArfiF. Gutowsky et al have also observed pure rotational transitions in ground vibrational state Ar3HF in the microwave 7.…”

Molecular Spectroscopy at Low Temperatures: A High Resolution Infrared Retrospective

“…65 With the pair potentials well determined, Ar n HF/DF provides a particularly good system for studying the transformation to a more fully solvated complex. Additionally, rotationally resolved spectra for Ar n HF/DF (n = 1−4) were already reported in Fourier transform microwave studies by Gutowsky and coworkers, [15][16][17][18]29 and infrared results have been reported for Ar n HF (n = 1 − 4) by McIlroy et al 21 Furthermore, comparison between theory and experiment for the equilibrium geometries of the complexes (shown for n = 1 − 3 in Fig. 5.2) and vibrational redshifts 11,22,66 provide critical tests of theoretical potentials.…”

“…Finally, some concluding remarks about possible future directions of such infrared studies are summarized in Sec. 16.…”

Tribute to Charles A. Schmuttenmaer

“…in Chemistry in 1985. While at UIUC, Charlie performed research with Prof. Herbert S. Gutowsky, studying the rotational spectra of gas-phase clusters composed of argon and HF . He then undertook Ph.D. studies at the University of California, Berkeley, where he worked with Prof. Richard J. Saykally on the development and implementation of far-infrared spectroscopy.…”
