Abstract:
The laser produced spectrum of Si(2) molecule is recorded for the first time using laser ablation technique in the region of 540-1010 nm. About 110 bands are observed in the entire spectral region and all these bands are classified into three band systems, viz. E-X, F-X and G-X of Si(2) molecule lying in the region of 814-1010 nm, 630-900 nm and 546-710 nm, respectively. All these electronic transitions take place from ground state X(3)Sigma(g)(-) state. The molecular constants of all these states have been determined.

IR Spectrum
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0% (complete...
