A review has appeared regarding the infrared and nuclear magnetic resonance spectroscopic investigations of quinolizidine alkaloids (303). The connection between the C/D ring junction and the existence of Bohlmann bands in the IR spectra of indolo[2,3-a]quinolizidines has been reinvestigated and interpreted (304). 

The reactions of tri-ATZ-butylplumbyllithium with various phosphorus chlorides have been investigated. For example, reaction of the lithium compound with diphenylchlorophosphane afforded hexa-tert-butyldiplumbane and tetraphenyldiphosphane as the isolated products. Analogous reactions with -butyl-substituted phosphorus chlorides yielded (tri-A, 7-butylplumbyl)di- -butylphosphane or tri- z -butylplumbyl(amino)-, t -butylphosphane. These and other molecules were characterized by multinuclear magnetic resonance spectroscopic studies.24...

Electron-nuclear double resonance (ENDOR) spectroscopy A magnetic resonance spectroscopic technique for the determination of hyperfine interactions between electrons and nuclear spins. There are two principal techniques. In continuous-wave ENDOR the intensity of an electron paramagnetic resonance signal, partially saturated with microwave power, is measured as radio frequency is applied. In pulsed ENDOR the radio frequency is applied as pulses and the EPR signal is detected as a spin-echo. In each case an enhancement of the EPR signal is observed when the radiofrequency is in resonance with the coupled nuclei.

Tables 3-2 and 3-3 summarize the infrared and proton-NMR (nuclear magnetic resonance) spectroscopic properties of alcohols and ethers. In the proton NMR, the oxygen atom is deshielding. Phenols and alcohols rapidly exchange protons so their NMR spectra are solvent dependant. The alcohol and ether groups don t have any characteristics absorptions in UV-vis spectra.

Larger oligopeptide hormones are also stabilized by such interactions. A nuclear magnetic resonance spectroscopic study of somatostatin by Hirschmann and co-workers (Arison et al., 1981) revealed that the side chains of phenylalanine-6 and phenylalanine-11 make the edge-to-face aromatic-aromatic interaction. Synthetic studies have shown that elimination of one or both of the aromatic groups at positions 6 and 11 abolishes biological activity. However, there is one notable exception. When...
