The conditions governing the H to H2 transition in interstellar medium are investigated by modeling the transfer of radiation in an idealized interstellar medium (ISM) consisting of diffuse clouds and self-gravitating clouds. The results of calculations showed that the transition depends sensitively on the pressure and radiation field, so that even a slight increase in the ambient pressure can convert a whole cloud population into H2 molecules without necessary converting the diffuse clouds into self-gravitating clouds. Similarly, a slight increase in radiation can convert the clouds back to H. The results imply that large regions of galaxies can spontaneously convert to molecular form following an interaction or other event that triggers mass accretion or an increase in the gas surface density.
