Infra Red Spectroscopy From messing with quantums we glean That symmetrical modes can't be seen Asymmetrical change Dipole moments derange And a sharp peak's revealed to the keen.
Raman Spectroscopy A laser makes the bonds vibrate Just like infra red does. But wait! With a polarized glow Only symetric modes show Which chemists find a useful traitBecause when both techniques are used on the same sample it can remove the need for dicking around with bond extinction coefficients and make structural analysis a matter of mental ball-and-stick topography. Result!
"Let's go to the ice-cap" he said. "We're British! We can't end up dead!" Well, the ice got a grip So we cut up the ship What we needed by then was a sled.
