The Infrared Spectra of Monoterpenes and Related Compounds

Abstract

The infrared spectra of 72 highly purified acyclic, monocyclic and bicyclic terpenes and their hydrogenated derivatives are presented. These spectra provide a broad basis for the correlation of structure and spectra.

Infrared Properties of Atmospheric Aerosol Constituents: Polyaromatic Hydrocarbons and Terpenes

“…The published transmittance spectra of terpenes (Mitzner et al, 1965(Mitzner et al, , 1968 provide key identifying features in the samples such as strong absorptions in the 10-11-pm range due to carbon skeletons along with weak peaks in the 10-11-pm range due to C = C stretching. Cyclic terpenes have additional absorptions in the 8-12-pm region.…”

Identification and Quantitative Estimation of Alcohols in Celery Essential Oil

“…The helium flow rate was 60 ml/min. Identifications were based on comparisons of the isolated compounds with infrared and mass spectra of authentic compounds (Hunter et al, 1966) and (Mitzner et al, 1968). Infrared and mass spectra were taken on a Perkin Elmer, Model 137 Infracord, and the mass spectra were taken on a Bendix Time-of-Flight, Model 3012, mass spectrometer.…”

ChemInform Abstract: CONSTITUENTS OF PEPPERS PART 6, THE OXYGENATED FRACTION OF PEPPER ESSENTIAL OIL

“…These caryophyllenols, which have also been mentioned as constituents of other essential oils, are also formed by photo-oxidation of isocaryophyllene (35), the more flexible cis-isomer of P-~aryophyllene~~. During this oxidation two other caryophyllenols (36,37) are also formed in respectable yield (resp. 19 and 21 % ) .…”
