Carbene intermediates are produced by the photolysis of diazomethane `(CH_2N_2)` or kenene `(CH_2 = C = O)`. They are also produced by the reaction of `CHX_3` with base or by Simmons-Smith reaction. There are two types of carbenes, singlet and triplet. They are so called due to their spin state.  Spin state of carbene is determined by using the formula :  where `S` is the sum of all electron spin numbers.
