Abstract:
Behavior of isolated caffeine in 60Co- γ radiation environment was studied in solid form as well as in aqueous medium. No degradation in solid caffeine structure was observed after exposing up to a dose of 10 kGy. In aqueous medium, 98% radiolytic degradation of caffeine was observed after application of 1.26 kGy γ dose. Radiation chemical yield decreased with increasing dose. The degradation was mostly favored in neutral medium. Addition of ethanol decreased the radiolytic degradation efficiency.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
