Ir wave number table absorption
WebO-1 CH 3 hydroxygen symmetry vibration produces IR absorption at the 2795 cm –1 peak. So, the fine components A-2, A-3, and O-1 have contributions to the amide A band. The other IR absorption peaks and the fine component calculated IR absorption peaks that contributed to the amide I, II, III, and A bands are listed in Table 1. Web3. Atmospheric absorption of solar and terrestrial radiation: (a) black-body curves for 6,000° K and 245° K ; (b) atmospheric gaseous absorption spectrum for a solar beam reaching ground level; (c) the same for a beam reaching the temperate tropopause (11 km. ) .
