Clearly structured into sixteen sections, it covers everything from spectroscopy in nanodimensions to medicinal applications, spanning a wide range of the electromagnetic spectrum and the physical processes involved, from nuclear phenomena to molecular rotation processes.
In addition to thermal stress, mechanical stress occurs due to the hindrance of molecular rotations and due to shear and tensile stresses of screw plasticizing and melt injection.
Just as a photographer has to use a shutter speed of one-thousandth of a second or less to snap clear pictures of a sprinter moving at 10 meters per second, chemists seeking clear "pictures" of fleeting molecular rotations and oscillations must use light pulses that are shorter than the time required for the motions, Smith explains.
