  • The benzene substituent is a C 6 H 5 fragment, so if you subtract that from C 9 H 12 you get C 3 H 7 (note that the benzene ring contains all 4 degrees of unsaturation: one for the ring and three for the three double bonds. This means you can have no more rings and no more double or triple bonds).
  • Infrared Spectroscopy 1. Introduction The light our eyes see is but a small part of a broad spectrum of electromagnetic radiation. On the immediate high energy side of …
  • The key then to distinguishing a monosubstituted benzene ring is a C-H wag between 770 and 710 cm-1 and the presence of a ring bend near 690 cm-1. As we will see, it is the position of the C-H wag and the presence or absence of the ring bending peak together that can be used to distinguish mono- and disubstituted benzene rings from each other.
  • This ability to detect the presence of benzene in the environment in small quantities means earlier detection of the hydrocarbon, making Panorama Synergy's technology key in the ongoing debates regarding hydraulic fracturing operations.
