These 4 files are written in simple ASCII mode. They contain the supplementary data for the paper: THE FIRST Si-H STRETCHING OVERTONE OF H3SiD. EMERGENCE OF LOCAL MODE EFFECTS. by G. GRANER, O. POLANZ, H. BUERGER, H. RULAND and P. PRACNA published in J. Mol. Spectrosc. XXX, xxx-xxx (1998) They contain the lists of observed and calculated wavenumbers for all the bands treated in this paper. Files strong.a1 and strong.e correspond to the bands (200,A1) and (200,E) respectively which yielded the parameters of Table 3. Files weak.a1 and weak.e correspond to the bands (110,A1) and (110,E) respectively which yielded the parameters of Table 5. In each file, the meaning of the different columns is the following: First column: an ordering number Second column: observed wavenumber (in cm-1) Third column: calculated wavenumber (in cm-1) Fourth column: difference of column 3 and 4 (in cm-1) Fifth column: uncertainty, in arbitrary units. The original weights, which take the values 1 0.1 0.01 0.001 and 0 can be retrieved by computing W = 1 /(uncert)**2 except for uncert = 0 which corresponds to W=0 Sixth column: assignment of the transition in the classical way: the first letter gives Delta K, the second one Delta J, the first number is J", the second one K". Note that there are a few "forbidden" transitions with Delta K = -2 or -3, denoted by the letters O and N respectively.
