In vibrational motion of HI (g), the iodine atom essentially remains stationary because of its relatively large mass. Assume that the hydrogen atom undergoes harmonic motion and that the force constant is 313.8 N/m
a) what is the fundamental vibrational frequency?
b) what is the fundamental vibrational frequency by D?
The Kb of 2,4,6-trimethylpyridine is 2.7x10-7 I've really been struggling with this stuff because i've been out of school sick, if there is any way that the steps can be shown in a more broad spectrum instead of ever little detail that would be ap..
