I need to know how to convert the rotational constant, B from Hz into cm^-1 for a paper i'm working on.....I'd be grateful if anyone can give me some suggestions, especially physics lecturers or physics majors. I know how its done, i just want to see is there moer than one way to tackle it....

It hurts to say Hertz (pun intended). When I received my physics degree in the '60's the brilliant minds of my fellow physicists decided to change the unit from the highly descriptive and SI units consistent cycles/sec = n/t = nf where n is the number of cycles divided by the number of t seconds passed for n cycles to the totally non-descriptive Hertz, which is not at all one of the kg-m-sec units we really need to be consistent. Notice that frequency, by definition, is f = 1/t Hz, which is simply the measure of one cycle in t seconds. All these non-descriptive units: pounds, Newtons, Hertz, Maxwells, Barns (yes there really is a Barn), and so on are arcane. More than that, they force people to spend extra time and energy learning what these arcane terms really are in kg-m-s and similar descriptive units. In other words, these arcane terms make learning physics and other hard science more difficult than need be.

You have to have the speed of the wave in the medium. Get the wavelength from
speed = wavelength * frequency.
Converet the wavelength into centimeters and take the recipricol.
