Rotational Spectroscopy

Rotational Spectroscopy. To a stationary observer, a rotating polar molecule looks like an oscillating dipole which can stir the electromagnetic field into oscillation. This picture is the classical origin of the gross selection rule for rotational transitions.

Wind Energy

Wind Energy. Wind Energy - the energy generated by wind. Wind energy in history. As early as 3000 B.C., people used wind energy for the first time in the form of sail boats in Egypt. Sails captured the energy in wind to pull a boat across the water.

Dynamic Braking of Induction Motors

Dynamic Braking of Induction Motors. Slow down a machine by converting kinetic energy stored in the rotating mass to heat energy in the rotor and/or stator windings. Switch the motor from the line to a braking circuit that causes the motor to behave as a generator with a connected load. .
