In IR spec, the spacing between the rightmost P-branch line and leftmost R-branch line is proportional to the square root of this value over the reduced mass.
In IR spec, the spacing between the rightmost P-branch line and leftmost R-branch line is proportional to the square root of this value over the reduced mass. This quantity can be generalized to a fourth-order tensor called the elasticity tensor, and in the isotropic case, it is the cross-sectional area of a material times (*) Young's modulus over the equilibrium length. The frequency of an oscillator is the square root of this quantity over mass. It is proportional to the stiffness for its namesake device, and force is equal to negative this constant times displacement. For 10 points, name this constant symbolized k that appears in Hooke's law.
