Resumen:
Most supernova remnants (SNRs) in our Galaxy are expected to be close to
their parent molecular clouds. The interaction between SNRs and
interstellar clouds not only alter the morphology and evolution of a SNR
but also heat, compress, disrupt or modify the chemistry of the cloud.
The turbulence generated in molecular clouds can trigger star formation.
Radio emission from atomic and molecular lines toward SNRs provide
unvaluable information to describe the ambient in which a SNR is
evolving and determine possible sites of SNR-interstellar cloud
interaction. The detection of OH masers in the satellite line at 1720can
set strong constraints in the characteristics of the shocked ambient
medium as well as on the dynamics of the SNR shock front. In this
article I review some relevant results derived from radio observations
in different spectral lines and under a variety of conditions towards
SNRs and their environments.
