AbstractThis work describes the measurement of hyperfine structure in a series of deuterated acetylenes via molecular-beam microwave spectroscopy. Measurements of spin-rotation constants were used to calculate the paramagnetic contribution to the chemical shielding of the concerned nucleus. Where possible, comparisons with NMR measurements were made. Measurements of the deuterium quadrupole coupling determined in this work are compared with previous measurements on the same or similar systems. A review of the theoretical work done in this area is presented as well as a discussion of trends observed from high precision measurements of deuterium quadrupole coupling. A computer program that calculates hyperfine structure for up to four coupling nuclei of arbitrary spin is presented.
