WebThe property of a compound being able to rotate the plane of polarization of plane-polarized light is called the optical activity, and a compound with such activity is labelled as optical active. A stereoisomer that is optical active is also called an optical isomer. Chiral compound is optical active. Achiral compound is optical inactive. WebSep 30, 2002 · We present measurements of amplified spontaneous emission (ASE) in films of spiro-sexiphenyl and higher branched spiro starburst compounds of the 1st and 2nd generation. Gain narrowing is observed at threshold intensities of approximately 3.2 μJ/cm 2 when pumped with 500 ps pulses at 337 nm. A comparison of ASE peak wavelengths, … WebIn most cases, the spiro atom is a carbon atom, and the rings are not in the same plane.
