Determining lowest energy isomeric structures
WebThe observed fragment ions form distinct fragmentation patterns, which lay down the foundation for the identification of isomeric 1,2,3-thiadiazoles and 1,2,3-triazoles. Recently, a more general, effective, and eco-friendly synthesis of variously substituted 1,2,3-thiadiazoles was developed [12]. WebThe isomeric shift (also called isomer shift) is the shift on atomic spectral lines and gamma spectral lines, which occurs as a consequence of replacement of one nuclear isomer by another. It is usually called isomeric shift on atomic spectral lines and Mössbauer isomeric shift respectively. If the spectra also have hyperfine structure the shift refers to the …
