In 1621, Willebrord Snell (1591–1626) developedSnell's law. It is the principle behind refraction and demonstrates the relationship between the incident ray, refracted ray, and the indices of refraction of the media. It is given by:
6, should lead a increment in total BSA adsorption by dense packag- ing mechanism43, hence (2) the conformational protein changes gradually weakened intermolecular electro- static repulsion, obeying the multilayer adsorption theory at the gas–liquid interface so that a higher level in ...
Using density function theory (DFT) based first principle computational studies combined with experimental data; we found that it is possible to unambiguously determine the participation of the functional hydroxyl group in Tyrosine in hydrogen bonding. In addition, we show that it possible to determine...

Multivariate calibrations namely partial least squares regression (PLS) and principle component regression (PCR) were developed for the prediction of sodium-FA using spectral ranges on the basis of relevant IR absorption bands related to sodium-FA. The sodium-FA content in soap formulations was ...
Also, and in order to encourage the manufacturers to upgrade this technology and invest in it, this research aims to study the basic principle of thermal decomposition of glass/PMMA and its synthesized volatile products using TG-FTIR and GC–MS measurements. In addition, the thermal decomposition...
FTIR difference spectra of GTP and GDP bound to Ras and Ras•GAP are complementary to X-ray structural analysis because they are obtained under more physio- logical conditions and are sensitive to structural details below the spatial resolution of X-ray crystallography. In principle, they are ...
Based on infrared radiation transmission theory and simple three-layer model, the noise equivalent radiation brightness (NESR) of infrared hyperspectral imaging system under area array detector is deduced. Three calculation methods of NESR are introduced. The principle experimental device of long-wave ...
Calculations on a serine crystal supercell 2 × 2 × 2 molecules deep appear to include, in a crude but fortuitously accurate way, enough of the principle out of phase dispersion to yield a match with experimental frequencies and intensities....
Principal component analysis(PCA) was used to determine the number of principle components(PCs). The score vectors of the PCs were analysed using the simple-to-use interactive self-modelling mixture analysis(SIMPLISMA) algorithm to obtain spectral and concentration profiles for the reactants, ...
