so in molecular bond, there are rotational and and virbrational energy
vibrational energy is given by
(n+1/2) h w
so what is vibrational energy for n=0 to n=1
?

I don't know what you mean. Do you mean how much energy does it require to excite the molecule into its n=1 mode of vibration?

pretty clearly just hw, right? Because n=0 is hw/2, and n=1 is 3hw/2.

why is it just hw not hw/2?

or are we subtracting?

when n = 0, E = hw/2. When n = 1, E = 3hw/2. In order to get from one to the other, the system needs to increase in energy by hw.

There are two types of bonds. Covalent and Ionic. In an ionic bond, electrons are lost and gained. In a covalent bond, electrons are shared.
