Okay, so this is about the bond strength, right? so basically, we know for the frequency, the frequency of the bond determines two things, right? one is the strength of the bond.
00:25
And the second is the mass of the atoms.
00:34
So usually the stronger of the bond, the higher the frequency.
00:39
However, the higher the mass, of the atom, right? the frequency would become lower.
00:45
So easily, right, from the amb, we can easily see carbon hydrogen bond is definitely, has a higher frequency than the cd bond because they have same bond stress because they are all carbon hydrogen single bond.
01:00
However, right, for the tutorial, it has a higher mass.
01:05
So definitely, say, h bond, right? the frequency is larger than the cd.
01:12
And for others, it becomes pretty easy...
