CO(2) laser coincidences with nu(3) of SiF(4) near 9.7 microm.
Doppler-limited tunable-diode laser spectra of the stretching fundamental (nu(3)) of (28)SiF(4) at 1031 cm(-1) have been analyzed and the spectroscopic constants determined. Explicit identifications have been made for transitions near CO(2) laser lines between 1023 and 1038 cm(-1); 51 such transitions have been observed in sub-Doppler saturation spectra obtained with a CO(2) laser. The closest observed coincidence is R(53) F(1)(9) of (28)SiF(4), at -1.391 MHz from (12)C(16)O(2)P(30). Implications for isotope-enrichment experiments are discussed.
