  Femtosecond transition‐state absorption spectroscopy of Bi atoms produced by photodissociation of gaseous Bi₂ molecules

  摘要：

  Femtosecond transition-state absorption spectroscopy has been performed on Bi atoms produced by the 308 nm photodissociation of Bi2 molecules contained in bismuth vapor. The transient spectra obtained are all clearly identifiable as atomic, yet they display striking asymmetries in line shapes and enhancements in intensity that clearly demonstrate that they are spectral signatures of atoms still in the force fields of their receding partners.

  The chemiluminescent emission from the Bi + F2 and Bi2 + F reactions has been characterized. A study of the chemiluminescent reaction of argon entrained bismuth vapor and molecular fluorine over a substantial pressure range (60–333 Pa) provides evidence for two distinct electronic transitions of BiF in the region 565–740 nm, at least one of which is thought to terminate in the BiF “1” (X21) state arising

  The equilibria involving the gaseous species SnBi, SnBi2, and SnBi3 above the condensed system Bi–Sn contained in a graphite cell have been investigated by the Knudsen effusion technique combined with mass spectrometry. Third law enthalpies for the reactions SnBin(g)=Sn(cond)+nBi(g), n=1–3, were evaluated. By combining the experimental reaction enthalpies with the appropriate thermodynamic data taken

• Chemiluminescent reaction of bismuth with F₂

  Chemiluminescent (CL) reaction of bismuth with F2 has been studied in a beam-gas arrangement under single-collision conditions. Time-of-flight (TOF) measurements suggest that the Bi2 dimer is the major beam reactant responsible for the observed CL. The bond dissociation energy of BiF has been estimated by observing the short wavelength limit in the B 0+—X10+ emission spectrum of BiF. The estimated lower bound of 3.7±0.1 eV is in good agreement with a recent determination of the bond dissociation energy of BiF. The vibrational distributions of the CL product states provide information on the potential energy surfaces governing the reaction.
