Answer to Question 1

Interstellar molecules are best observed and studied through their radio emissions because most interstellar molecules are located in cold molecular clouds. In these locations molecules are rarely excited by any means except rotation and vibration. These excitations are very low-energy. Because of the low energy involved in these excitations, very low energy photons are emitted.

Answer to Question 2

TRUE
