Figure 13C NMR Spectrum 125 MHz CDCl3 of the Probe CID7694069ML229 - Probe Reports from the NIH Molecular Libraries Program. Deuterated chloroform is by far the most. The infrared spectra for the fundamental absorption bands ν1 ν2 ν4 and ν5 of CHCl3 and CDCl3 have been measured in polycrystalline films.

The sample of CDC13 was a Fluka reagent puriss. 13C Chemical Shifts and Infrared Absorption Frequencies in Heterocyclic N-Oxides HETEROCYCLES. CDCl3 have also been studied over the entire concentration range.

Deuterated chloroform CDCl 3 also known as chloroform- d is an isotopically enriched form of chloroform CHCl 3 in which most of its hydrogen atoms consist of the heavier nuclide deuterium heavy hydrogen D 2 H rather than the natural isotopic mixture in which protium 1 H is predominant. J-values are listed next to the peaks for some examples. 198 NMR 17 FTIR 2 Raman and 20 MS.

The integrated intensities of the fundamental ir absorption bands of CHCl3 and CDCl3 have been measured using the pressure-broadening technique. When dissolved in CDCl3 compound K with the molecular formula C4H8O2 gives a 1H NMR spectrum that contains a doublet at δ 135 a singlet at δ 215 a broad singlet at δ 375 1H and a quartet at δ 425 1H. Splittings due to the four chlorine siotropic molecules have been resolved for the ν 3 A 1 bands of both CHCl 3 and CDCl 3After taking isotopic effects into account further splittings of the fundamentals in the Raman spectra together with those previously recorded in the infrared.
