CM homologues

If the wavenumber of a C-H stretching band in the infrared spectrum of a certain compound is 2960 cm-1, calculate the wavenumber of the corresponding C-D stretching band in the deuterated homologue. 

Ford CM, Boss PK, Hoj PB (1998) Cloning and characterization of Vitis vinifera UDP-glucose flavonoid 3-O-glucosyltransferase, a homologue of the enzyme encoded by the maize bronze-1 locus that may primarily serve to glucosylate anthocyanidins in vivo. 1 Biol Chem 273 9224-9233... 

Isoprenyi glyceryl ethers archaeol-like (archaeol Cm-C ), comprising C20-C25 and C25"C25 homologues (an extreme halophilic, thermoacidophilic, and methanogenic Archaea Kates 1993 caldarchaeol-like (caldarchaeol monocyclic C o-C ), comprising bicyclic structures from thermoacidophilic and methanogenic Archaea Kates 1993. (Archaea in bold ce are not meant to be exclusively marine). 

Seventeen IR vibrational bands (At matrix, 12-15 K) were observed and assigned to oxasiliranylidene 60 on the basis of their similarity to calculated values (Section 1.17.4.2). Isotopic shifts were measured for the homologue and were consistent with the assignments <19990M2155>. IR vibrational bands at 1024, 942, 826, 763, and 729 cm were assigned to oxasilirane 64 on the basis of their similarity to calculated values (Section 1.17.4.2). The methyl-substituted version showed bands at 2110, 1006, and 935 cm (At matrix, 12-15 K) <2000JOM248>. 

The detector signal is much more dependent on specific compound properties in liquid chromatography than it is in gas chromatography. For example, the UV signal is a function of the molar absorptivity, which varies between 0 and 10 0001 mol cm depending on the compound used. The molar absorptivity and absorbance maximum also vary between homologues. Hence at least one calibration chromatogram must be obtained for each quantitative analysis. ...
