Rabuyu chapter 32IR Spectroscopy Tutorial: Aldehydes The carbonyl stretch C=O of saturated aliphatic aldehydes appears from 1740-1720 cm -1 . As in ketones, if the carbons adjacent to the aldehyde group are unsaturated, this vibration is shifted to lower wavenumbers, 1710-1685 cm -1 . A good general reference for more detailed information on interpretation of infrared spectra (as well as other spectroscopic techniques) is Silverstein, R.M.; Bassler, G.C.; and Morrill, T.C. Spectrometric Identification of Organic Compounds. 4th ed. New York: John Wiley and Sons, 1981.

This GCSolv grade solvent is a Spectrum brand high purity solvent specifically controlled for use GLC techniques and has a 2,5-hexanedione is a diketone that is hexane substituted by oxo groups at positions 2 and 5. It is a toxic metabolite of hexane and of 2-hexanone It has a role as a human xenobiotic metabolite and a neurotoxin. It is a diketone and a methyl ketone. It derives from a hydride of a hexane. Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments.

Alkyl halides are compounds that have a C–X bond, where X is a halogen: bromine, chlorine, fluorene, or iodine (usually Br or Cl in the organic chemistry teaching labs). In general, C–X vibration frequencies appear in the region 850-515 cm-1, sometimes out of the range of typical IR instrumentation. A 0.5-ml volume of n-hexane was added to the DMSF, and the n-hexane-soluble component was recovered. This process was repeated three times. The soluble component and the residue were designated as the n-hexane-soluble fraction (n-HSF) and n-hexane-insoluble fraction (n-HISF), respectively. These fractions were evaporated to dryness by rotary ... Ultraviolet Spectroscopy CH521’Course’on’Interpretave’Molecular’Spectroscopy;’Course’Instructor:’KrishnaP.’Kaliappan’!
