Abstract

We demonstrate the diagnostic value of para-formaldehyde (p-H2CO) as a tracer of the density and the temperature of the molecular gas in external galaxies 
using the prototypical starburst galaxy M 82 as an example. 
We also report the discovery of the methanol line CH3OH(42 → 31, E) from M 82.
