IR spectrum of methanol...?

It is found that the IR spectrum of methanol contains a peak at 2300 cm-1 and it is "going up". WHat is the source of this peak and why is it "going up"?

I'm not sure what you mean by "going up" but methanol ( or alcohols in general) typically has C-H stretching around 2500 and then an -OH stretch around 3000.

If any part of an IR spectrum is "going up", it means absence of absorption, and can be used to deduce that a particular functional group is definitely not there. Peaks in IR hang downwards.
