5.80 Small-Molecule Spectroscopy and Dynamics (MIT)
The goal of this course is to illustrate the spectroscopy of small molecules in the gas phase: quantum mechanical effective Hamiltonian models for rotational, vibrational, and electronic structure; transition selection rules and relative intensities; diagnostic patterns and experimental methods for the assignment of non-textbook spectra; breakdown of the Born-Oppenheimer approximation (spectroscopic perturbations); the stationary phase approximation; nondegenerate and quasidegenerate perturbatio

Multiplying Rationals
Multiplying rational expressions is basically two simplifying problems put together. This video clip explains how to multiply rationals by factoring both numerators and denominators and identifying equivalents of one to cancel. Dividing rational expressions is the same as multiplying with one additional step—we take the reciprocal of the second fraction and change the division to multiplication. (1:41)

Central Angles
This video explains how a central angle is an angle where the vertex is on the center of the circle and the endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles. (2:12)

Inscribed Angles
This video describes how inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc. Inscribed angles that intercept the same arc are congruent. (1:44)

Angles in Semicircles
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees. This video describes how angles in a semicircle can be used to find missing missing angles and lengths. Pythagorean's theorem can be used to find missing lengths (remember that the diameter is the hypotenuse). Also, the measure of an angle formed by a chord to a tangent is half the intercepted arc.
