Sulfanyl (HS•), also known as the mercapto radical, hydrosulfide radical, or hydridosulfur, is a simple radical molecule consisting of one hydrogen and one sulfur atom. The S-H distance in the radical is 0.134 nm. The radical is also proposed to be formed by the action of ultraviolet radiation on hydrogen sulfide. A wavelength of 190 nm gives maximum absorption.
