Vibrational spectra of diatomic molecules
October 25th, 2016Let’s perform the interpretation of the vibrational spectra of diatomic molecules with use of quantum harmonic oscillator model (fig.1):

Band structure of optical semiconductors
October 18th, 2016The training of specialists in the field fiber-optic communication lines involves the study of such difficult topics as “Light-emitting diode (LED)” and “Semiconductor Lasers” (Zvelto, 1990). Clarification of the physical foundations of these devices requires the use of educational information which is studied in the course of quantum chemistry. Read the rest of this entry »

January 5th, 2012The equation of rectilinear uniform motion
January 5th, 2012 Given that the trajectory of a material point (MP) motion is a straight line, the motion is called “a rectilinear motion”. The rectilinear motion can be described by the one-dimensional coordinate system. Let us suppose that at time 
Then the position of the MP at time
