Determination of the molecular structure of Sulphonyl Chloride Isocyanate using microwave spectroscopy
… spectrum of SO₂CINCO was assigned for two isotopic species, SO₂³⁵CINCO and SO₂³⁷CINCO, by considering the Stark effect and the nuclear quadrupole splittings due to chlorine and nitrogen. Rotational constants and nuclear quadrupole coupling constants were determined from the assigned peaks. …

Structure and dynamics of small clusters studied by microwave spectroscopy
… diborane-HCl. This tunneling only occurs in the isotopic species that are homonuclear with respect to the borons. DCl substitution also quenches the tunneling. This leads to the surprising conclusion that diborane subunit undergoes a geared motion with the HCl subunit in which the HCl travels …

Structure and microwave spectrum of the 2-cyano-2-propyl radical
… spin rotation constants determined for the two species were E<sub>aa</sub>=-69.9, E<sub>bb</sub>=-36.1, E<sub>cc</sub>=2.7Mhz and E<sub>aa</sub>=-55.4, E<sub>bb</sub>=-32.6 Mhz for (CH₃)₂CCN and (CD₃)₂CCN respectively. The hyperfine coupling constants for ¹⁴N are identical for both isotopic …

Spectroscopic and theoretical studies of small molecules.
… out and complete analyses performed to the A1 species vibrations v1-v4, allowing the determination of revised vibrational frequencies and rotational parameters. Perturbations found to be present in all bands were elucidated and identified with the aid of H2C13CO, H213CCO and D2CCO isotopic …
