1. A gas phase molecules of HCl has a bond length of 127.5pm (Cl=35, H=1). As it rotates in space what is its zero-point energy?
what is the smallest amount of energy that this molecule can absorb in rotational excitation? what wavelength of light would that be?
what portion of the electromagnetic spectrum is that in?
2. The larger molecule HI has a bond length of 160.92 pm (H=1, I=127). its bond's force constant is 314 N/m.
what are the frequencies of light for that will excite the lowest energy rotational and vibrational translations?
what regions of the electromagnetic spectrum are these in?
