Simply by observing the existence of the Cherenkov radiation from a particle, one can determine its relative velocity with respect to the light speed in medium. Knowing that, one can determine the particle momentum.
It is a ring formed carbon skeleton. The smallest possible cyclic hydrocarbon is cyclopropane (triangular C3H6) together with cyclobutane both being rather unstable (degration to linear propene and 1-butene). Five and six membered rings are quite common.
HYDROCARBONS. These compounds form the simplest form of lipids, they contain only carbon and hydrogen. They may be divided into aliphatic hydrocarbons with a carbon chain which may be linear (normal), branched, saturated (alkanes) or unsaturated (alcenes), cyclic hydrocarbons and carotenoids.YDROCARBONS.
