B = h/(8 π2 c I)
Where B is the rotational constant (cm-1)
h is Plancks constant (gm cm2/sec)
c is the speed of light (cm/sec)
I is the moment of inertia (gm cm2)
Enter a rotational constant or a moment of inertia in the appropriate box below and press the adjacent calculate button. The related quantities will appear in the other boxes.
