This paper is a continuation of earlier work in which the high resolution infrared spectrum of [1.1.1]propellane was measured and its k and l structure resolved for the first time. Here we present results from an analysis of more than 16,000 transitions involving three fundamental bands v₁₀ (E' - A'₁),...
The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via
high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric
SO stretching Q-branches observed by the latter are quite different, being especially complex for
³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...
The strained carbon ring, bicyclo[1.1.1]pentane, was synthesized by a reaction between
1-(phenylsulfanyl)bicyclo[1.1.1]pentane, prepared from propellane, and Raney nickel.
Infrared spectra were recorded at a resolution of 0.0015 cm-1, a resolution significantly
better than previous measurements, 0.06 cm-1. A single fundamental band was analyzed
to determine the ground state and excited...
High resolution spectroscopy was used to study the properties of two simple
polyatomic molecules, sulfur trioxide, SO₃, and carbon suboxide, C₃O₂.
The fundamental modes and several hot bands of the ¹⁸O isotopic fonns of
SO₃ (³²S¹⁸O₃ and ³⁴S¹⁸O₃) have been investigated using both infrared spectroscopy and coherent anti-Stokes Raman scattering...
The high resolution stimulated Raman spectrometer at OSU was
modified to improve its sensitivity and to extend its range of
applications to low Raman shifts and to the spectroscopy of solids and
liquids. As part of the characterization of the spectrometer, optical
Stark effects on rotational and vibrational transitions of...
Interesting rovibrational characteristics of two D_(3h) oblate symmetric top molecules were studied. Hamiltonian models for the fine rovibrational level structure of [1.1.1]propellane (propellane) were obtained for many low-lying modes. Ground state parameters (GSP) that are not exclusively K^(2n) dependent were obtained. Initially, the GSP were used in conjunction with density...
