WebIn an asymmetric stretch, they are going in opposite directions. One bond gets longer as the other gets shorter, so the change in dipole moment is much less. It takes energy to separate positive and negative charges from each other, so the symmetric vibration has a higher frequency (energy). 2 comments. WebWithin certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke's law and commonly written: \boxed {F=-kx} F = −kx. Where F F is the force, x x is the length of extension/compression and k k is a constant of proportionality known as ... grace cox facebook
