This website includes zenith absorption/optical thickness and limb radiance spectra on fully interactive graphs which can be customised show specific molecules, spectral ranges and satellite bands. Spectra are calculated using the RFM ... Webgives both reflectance and transmittance of a 100.um high-density polyethylene foil. The reflectance is the wedge which can separate the real and imaginary parts of the refractive index. At 2.5.um, the reflectance plus the transmittance is 100 %. leaves no room for loss; thus the extinction coefficient at 2.5.um

6.3: IR Spectrum and Characteristic Absorption Bands

WebThe IR spectrum plays an important role and provides valuable information related to the functional groups in pentacyclic triterpenoids. IR spectra of triterpenoids have two characteristically regions. Absorption bands in the region 3500–3650 and 2650–3350 cm − 1 are due to OH stretching and –CH stretching, respectively. WebAn infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
