IR and Raman spectra (organic substancesThe Fourier‐transform spectrum of the CH3OH overtone C–O stretching band (vCO=2←0) has been recorded in the range 1950–2060 cm−1, at a resolution of 0.004 cm−1. The spectrum is resolved intoJmultiplets, each displaying complicated substructure...
Laser-Stark spectra have been observed for methyl alcohol using the 311 μm line of the HCN laser. Partial assignments are presented for the three most distinctive structures in the spectra. The low field structure is clearly associated with a member of the J=2019 q R a -type multiplet, an...

The IR spectrum of hydroxypropyl methylcellulose (Fig. 2B) shows a characteristic peak at 3475 cm−1 due to OH and a peak at 2935 cm−1 due to C–H aliphatic stretching [2, 34]. The IR spectra of the quetiapine fumarate and hydroxypropyl methylcellulose physical mixture (Fig. 2C) ...
Determination of epidemiology and antimicrobial susceptibility of extended spectrum beta lactamase producing uropathogens Several studies have documented the suitability of methyl red dyed polyvinyl alcohol in the dose range 10-55 kGy [6], as the film was exposed to gamma radiation it changes from the...
Pseudoesters, for example, 221, in which the alcohol portion is a fragrance (such as geraniol), have been developed for the slow release of scent. Alkaline hydrolysis of compound 221 requires time so that the rate at which scent is released is prolonged over that of simple evaporation <2001...

3-Methyl-1-butanol, with the chemical formula C5H12O and CAS registry number 123-51-3, is a compound commonly known as isoamyl alcohol or isopentyl alcohol. It is a colorless liquid with a strong odor, often described as having a fruity or fusel-like aroma. Industrially prepared by rect...
Aging and drying process are accompanied by the loss of solvent (alcohol, water), which increases the strength and decreases porosity. When drying is performed under ambient conditions, the resulting composite is called a xerogel. An aerogel is formed when the sol is processed under supercritical ...
