Consider the Hooke's Law expression on p. 689 If you plug in the value of the constants (your book ignores Avagradro's number which needs to go in there), the expression becomes that shown below. As you can see, you can actually calculate the wave numbers for an infrared vibration for a chemical bond if you only knew the force constant for that bond. The carbon-hydrogen stretch in the compound chloroform, H-CCl_3, is at 3035 cm^-1. Using the Hooke's Law formula shown above, what would you calculate the carbon-deuterium stretch in the compound deuterochloroform, D-CCl_3? Assume that the force constant for the carbon-hydrogen and carbon-deutero bonds are the same.
