Deuterated propane
WebThe advantage of this method was that at 3.97 # the liquid product from non-deuterated propane had almost negligible absorption, which was easily compensated for by introduction of a neutral filter in the comparison beam. There was thus no need to convert the products to pure water or to pure hydrogen for the estimation of the deuterium. WebNeglecting the non-statistical distribution of multiply deuterated propane (a trivial contribution to overall D abundance in natural samples; e.g., a 10 ‰ enrichment in the doubly deuterated propane would only increase εDC-T by 0.005‰), the above nomenclature is equivalent
