The absorption spectroscopy of the lowest pseudorotational states of tetrahydrofuran

چکیده
The rotational structure of the pseudorotational (PR) band n = 0 → n = 2 has been observed in jet-cooled tetrahydrofuran (THF) in the 170-360 GHz frequency range. The observed transitions were analyzed together with the previously obtained microwave data of Meyer and co-workers [R. Meyer, J. C. Lopes, J. L. Alonso, S. Melandri, P. G. Favero, W. Caminati, J. Chem. Phys., 111, 7871 (1999)]. The experimentally observed transitions provide direct spectroscopic evidence of the symmetry ordering of the lowest 4 observed

Observation of bands among the four lowest pseudorotational states of 1,3-Dioxolane
The rotational transitions belonging to the pseudorotational bands n = 0→1, n = 2→3, and n = 0→3 has been experimentally observed for 1,3-dioxolane in the spectral region of 153-364 GHz in a supersonic jet environment using the FASSST absorption spectrometer. Based on these observations, the symmetry ordering and the energy spacings of the four lowest states, n = 0,1,2,3, have been established....
متن کاملNear-infrared photoabsorption by C60 dianions in a storage ring.
We present a detailed study of the electronic structure and the stability of C(60) dianions in the gas phase. Monoanions were extracted from a plasma source and converted to dianions by electron transfer in a Na vapor cell. The dianions were then stored in an electrostatic ring, and their near-infrared absorption spectrum was measured by observation of laser induced electron detachment. From th...

ABSTRACT The solvatochromic behaviour of two ketonic derivatives of benzodiazepine namely 7-chloro-1-methyl-5-phenyl-1,5-benzodiazepine-2,4-dione (Clobazam®) and 5,(2-chlorophenyl)-7-nitro-2,3-dihydro-1,4-benzodiazepine-2-one (Clonazepam®) were analysed in some selected solvents of different polarities using UV-Visible spectroscopy and DFT computational techniques. The solute-solvent interacti...
متن کاملProbing the Structure, Pseudorotation, and Radial Vibrations of Cyclopentane by Femtosecond Rotational Raman Coherence Spectroscopy.
Femtosecond time-resolved Raman rotational coherence spectroscopy (RCS) is employed to determine accurate rotational, vibration–rotation coupling constants, and centrifugal distortion constants of cyclopentane (C5H10). Its lowest-frequency vibration is a pseudorotating ring deformation that interconverts 10 permutationally distinct but energetically degenerate "twist" minima interspersed by 10 ...

Evidence for the self-aggregation of 10(S)-chlorophyll a (= chlorophyll a') in nonpolar solvents has been obtained by means of absorption spectroscopy in the visible and infrared regions. The visible absorption spectrum of chlorophyll a' exhibits a shoulder at 680 nm in aliphatic hydrocar bon solvents and the infrared spectrum measured in carbon tetrachloride contains an “aggrega tion peak” a...
