Abstract
Methyl formate (HCOOCH$_3$) is an abundant interstellar molecule, found almost everywhere in the star-forming region. _x000d_ The interstellar abundance of the $^{13}$C is about 1/50 of $^{12}$C. _x000d_ The $^{13}$C substituted methyl formate in the ground and first excited states were already found toward massive star-forming_x000d_ regions including Orion KL. _x000d_ $footnote{C.
