FIG. 2.

Effect of the presence of nitrogen on the spectra of HCl and HXeCl in a Xe matrix. (a) Absorption spectra of and HCl/Xe matrices in the HCl region deposited at 30 K. The main bands of HCl are equalized for better comparison. (b) Effect of annealing at 45 K. The main bands of HXeCl are equalized for better comparison. The and HCl/Xe matrices were preliminarily photolyzed by 193 nm light. The bands are marked with C. A weak absorption at (shift of ) may also belong to the same complex. The spectra were measured at 8.5 K.

FIG. 3.

Effect of the presence of nitrogen on the spectra of HBr and HXeBr in a Xe matrix. (a) Absorption spectra of and HBr/Xe matrices in the HBr region deposited at 30 K and difference between them (lower trace). The main bands of HBr are equalized for better comparison and for the purpose of subtraction. (b) Effect of annealing at 60 K (two upper spectra) and difference between them (lower trace). The assigned bands are marked with C. A weak band at (shift of ) may also belong to the same complex. The bands marked with asterisk and L belong to the complex (Ref. 13) and libration motion of HXeBr in solid xenon (Ref. 21). The main bands of HXeBr are equalized for better comparison and for the purpose of subtraction. The and HBr/Xe matrices were preliminarily photolyzed by 193 nm light. The spectra were measured at 8.5 K.

FIG. 4.

Effect of deposition temperature on the spectra of HCl and HXeCl in a Xe matrix in the presence of nitrogen. (a) Absorption spectra of matrices in the HCl region deposited at 35 and 45 K. The main bands of HCl are equalized for better comparison. (b) Effect of annealing at 45 K for the two deposition temperatures. The assigned bands are marked with C. The main bands of HXeCl are equalized for better comparison. The and HCl/Xe matrices were preliminarily photolyzed by 193 nm light. The spectra were measured at 8.5 K.

FIG. 5.

Effect of deposition temperature on the spectra of HBr and HXeBr in a Xe matrix in the presence of nitrogen. (a) Absorption spectra of matrices (two upper spectra) in the HCl region deposited at 30 and 40 K and of an HBr/Xe matrix deposited at 40 K (lower spectrum). The main bands of HBr are equalized for better comparison. (b) Effect of annealing at 60 K of these three matrices preliminarily photolyzed by 193 nm light. The bands are marked with C. The main bands of HXeBr are equalized for better comparison. The spectra were measured at 8.5 K.
