WebDec 1, 1993 · In this paper we describe an approach to predict infrared spectral data of simple organic compounds by processing their numerically encoded molecular graphs using neural networks. The goal is to provide a tool for pruning the list of tentative candidate structures by a plausibility test in the spectra space. 0925-5281/93/$06.00 0 1993 - …

WebThis condition can be summarized in equation (2) form as follows: (2) Vibrations that satisfy this equation are said to be infrared active. The H-Cl stretch of hydrogen chloride and the asymmetric stretch of CO 2 are examples of infrared active vibrations. Infrared active vibrations cause the bands seen in an infrared spectrum. WebMass spectrum: molecular ion at 152 & 154 (approximately equal intensity peaks) additional peaks at 107 & 109 (equal intensity) largest peak at 59. 13C NMR: peaks at 70, 66, 30, and 15 ppm. 1H NMR : a 3.7 ppm , 2 H , triplet b 3.5 ppm , 2 H , quartet c 3.4 ppm , 2 H , triplet
