Introduction,cture of organic compounds. It consists of reference data, spectra, and empirical correlations from .H, .C, .F, and .P nuclear magnetic resonance (NMR), infrared (IR), mass, and ultraviolet–visible (UV/Vis) spectroscopy.

13C NMR Spectroscopy, increments (Z) for substituents in α, β, γ, and δ position (see next pages). Some substituents occupy two positions. Thus, the quaternary carbon atom . in the example given below is in δ position relative to the carbon atom . since the ..-hybridized oxygen of the β-COO group occupies the γ position作者: 直言不諱 時(shí)間: 2025-3-22 06:18 作者: esculent 時(shí)間: 2025-3-22 12:36 作者: Juvenile 時(shí)間: 2025-3-22 13:31

Heteronuclear NMR Spectroscopy,To estimate the .F chemical shifts of substituted 6-ring heteroaromatics, the same increments, Z., can be used as for substituted fluorobenzenes (see preceding page). However, different base values, Y (as given below), apply depending on the number and position of nitrogens and the position of the fluorine substituent in question.作者: agglomerate 時(shí)間: 2025-3-23 19:17 作者: inflame 時(shí)間: 2025-3-23 22:19
Mass Spectrometry,. Larger alkyl fragments (with C.) are chiefly formed by direct cleavage. They dehydrogenate and undergo substantial H and skeleton rearrangements. Smaller alkyl fragments (C. to C.) are mainly formed by secondary decomposition of higher alkyl fragments. Eliminations of groups from within the chain (and recombination of its ends) also occur.作者: NATAL 時(shí)間: 2025-3-24 06:12
UV/Vis Spectroscopy,The π→π. transition of conjugated double bonds is above ≈200?nm with typical intensities of the order of log ε ≈ 4. Its position can be estimated with the Woodward–Fieser rule. For cross-conjugated systems, the value for the chromophore absorbing at the longest wavelength has to be calculated.作者: 施舍 時(shí)間: 2025-3-24 09:09
