The absorption of the x rays from a supernova explosion in the surrounding molecular gas is discussed. A supernova explosion in a molecular cloud results in a supernova remnant which radiates a fraction of the approximately 10 to the 51st power erg kinetic energy of the supernova explosion in the form of x rays. The absorption of these x rays in the surrounding molecular gas produces ionization, dissociation, and heating. It is found that a 1051 erg supernova explosion in a uniform molecular cloud of density equal to 1000 per cubic centimeter results in the emission of photons in the H2 line. This process may contribute appreciably to the strong S(1) line emission seen from some starburst galaxies, such as NGC 6240.
