I read to use ammonia to basify silica gel (for acid labile compounds).
I was wondering why not NaOH, etc.? (In alcohol).

It is said that peaks in near infrared region are smaller and wider
than in mid infrared because they correspond to overtones (and combinaison)
of fundamental vibrations which occur in the mid infrared.
I can understand from energetic level population why peaks are smaller
