Extremely rare : A CS triple bond can be assigned to HCSOH, a new molecule prepared from H 2 CSO by a photochemical [1,3]H‐shift. But does this formal description agree with analyses on the basis of IR vibrations, bond lengths, bond orders, molecular orbitals, and compliance constants? Molecules like this challenge and refine our current understanding of chemical bonding.
