Infrared, nuclear magnetic resonance, ultraviolet, optical rotary dispersion and circular dichroism measurements have been used for the spectral analysis of thiiranes. A few steroidal thiiranes have been reported to possess infrared absorption in the range from 580 to 700 cm The intermediate thiocyanate derivatives (RSCN) have a strong sharp peak at 2130-2160 cm the isomeric isothiocyanate (RNCS) shows a much stronger but broad band at 2040-2180 cm. ... 

Nuclear magnetic resonance (NMR), irrfrared (IR) and optical rotary dispersion (ORD) spectroscopy studies have demonstrated that D-glucopyranose units have the same conformation in both dimethyl sulfoxide (DMSO) and heavy water (D2O). The spectroscopic studies on CDs in aqueous solution suggest that the conformation of CDs in the solution is almost identical to their conformation in the crystalline state. j8-CDs have perfect symmetry, while a- and y-CDs rings are slightly distorted. The planar structure of a-CDs in solution deviates by about 100 pm from that in the crystal structure. The twist form observed experimentally in the glucose unit number five out of the plane of the five other glucose units disappears in solution [4,9].
