Infrared Spectra of Methanol, Ethanol, and rz-Propanol
The infrared absorption spectra of methanol, ethanol, and n-propanol have been measured with prism instruments. Studies have been made of the vapors and of several dilute solutions. The methanol spectra, between 2 to 15 microns, prpvided a direct comparison with the other two alcohols and confirmed earlier work on the existence of a number of lowintensity bands. The two other alcohols were stud...
متن کاملEvaluation of Ethanol and N-propanol in Victims
Background: Blood alcohol concentration is a major factor in forensic analysis in criminal and civil litigation. Along with ethanol, other volatile compounds such as n-propanol are produced as products of putrefaction. The aim of this study is the evaluation of ethanol and n-propanol in postmortem blood. Methods: A case-control study was done on 300 blood samples obtained from cadavers that...
متن کاملDominant Association Species in Binary Mixtures of Methanol, Ethanol and Propanol in Nonpolar Solvents
The molecular associations in the binary mixtures of (methanol/solvent), (ethanol/solvent) and (propanol/solvent) were studied using NMR, FTIR and VLE data at different temperatures. The activity coefficients as the most important quantities representing the mixture deviation form ideal behavior were evaluated by using various association models to express the physical and chemical contribution...

متن کاملCalculated Infrared Spectra of Hydrogen-Bonded Methanol–Water, Water–Methanol, and Methanol–Methanol Complexes
Ab initio calculations at the B3LYP/aug-cc-pVDZ, B3PW91/aug-ccpVDZ, MP2/aug-cc-pVDZ, B3LYP/6-311 G(2d,2p), B3PW91/6-311 G(2d,2p), and MP2/6-311 G(2d,2p) levels are performed for the IR spectra of isolated water and methanol molecules and hydrogen-bonded water–methanol, methanol–water, and methanol–methanol complexes. Frequency shifts and changes in intensities are obtained for the proton donor ...
