Infrared spectrum of ketones. Ketones show a very strong absorption band at 1700 due to stretch vibration of the carbonyl.

2018年1月2日 · To distinguish between diphenyl ketone (benzophenone) and benzaldehyde using infrared (IR) spectroscopy, one can focus on the characteristic absorption frequencies of their functional groups. Benzaldehyde features an aldehyde functional group, whereas diphenyl ketone features a ketone functional group.

2016年1月4日 · Diphenyl ketone (DPK), a semi-organic nonlinear optical material, has been synthesized

Conjugation of the carbonyl group with carbon-carbon double bonds or phenyl groups, as in alpha, beta-unsaturated aldehydes and benzaldehyde, shifts this band to lower wavenumbers, 1685-1666 cm -1. See also: The spectrum of 2-butanone is shown below. This is a saturated ketone, and the C=O band appears at 1715.

Diphenyl ketone (DPK), a semi-organic nonlinear optical material, has been synthesized and single crystals were grown from alcohol – ethanol solution at room temperature up to dimensions of 4.5cm×4.5cm×4cm. The unit cell parameters were determined from single crystal and powder X-ray diffraction studies.

2012年9月1日 · The analysis of the infrared and Raman spectra of 1,3-diphenylurea suggests the presence of a second near-planar cis–trans structure with very low conformational abundance at room temperature. For 1,3-diphenylacetone the observed spectra were consistent with the presence of only one conformation in the solid phase.

Most of the infrared spectra were produced from thin liquid films, a few involve the vapour of low boiling compounds and the infrared spectra of solids can be obtained from a compressed disc of the organic compound in a two layered potassium bromide KBr disc.
