Determination of the Ring-Inversion Barrier in y-Thiobutyrolactone by Microwave Fourier Transform Spectroscopy
نویسندگان
چکیده
The microwave spectrum of y-thiobutyrolactone has been reinvestigated using microwave Fourier transform spectroscopy. The /ic rotation inversion transitions have been found to be splitted for the first excited state of the vibration at ~ 250 c m 1 . An inversion splitting of 0.014 MHz has been measured directly from these transitions. These splittings indicate that the vibration is related to a double minimum potential function describing two ring-twisted conformations connected by inversion. A one-dimensional reduced potential function has been derived for this vibration and gives a barrier to ring inversion of 1380± 350 cm" \

A method is described by which it is possible to determine the high barrier to ring inversion and hindered rotation by neat racemization of optically active compounds when the racemization is caused by ring inversion or hindered rotation. The method is based preparation of sufficiently pure enantiomers, mainly by chromatography on swollen microcrystalline triacetylcellulose (TAC). By this t...

Z. Naturforsch. 55 a, 481^185 (2000); received February 9, 2000 We have performed an investigation of the internal rotation of the methyl group in trans-cis ethyl vinyl ether by using molecular beam-Fourier transform Microwave (MB-FTMW) spectroscopy. Rotational spectra (up to J = 20) were recorded in the frequency region 4 -19 GHz. Due to the internal rotation of the methyl group, some rotation...
متن کاملMicrowave Spectrum of y-Thiobutyrolactone
The microwave spectrum of y-thiobutyrolactone has been observed and measured in the vibrational ground state and in several excited states of the ring-bending and ring-twisting modes. From the value of the /ic component of the dipole moment and inertial-defect considerations the ring skeleton was shown to be non-planar. The average intensity ratio for the rotational transitions between the grou...
