Figure 7. A summary of some P—O—alkyl groups. R1 is P-alkyl and R2 is P-O-Alkyl. The compared compounds belong to the sarin (1 alkyl alkylphosphonofluoridates), the tabun (2 dialkylamino alkyl phosphoramidocyanidates), and the dialkyl methylphosphonate (4) families. There are two peaks (1185-1180cm 1 and 1072-1070ctrr1) in the tabun family (2) spectra in addition to the C-O peaks. These peaks are due to the C-N bond. The dialkyl methylphosphonate compounds (4) listed here are symmetric (R2 = R2 ) (Reproduced by Permission of Springer-Verlag from M. T. Soderstrom, R. A. Ketola, Fresenius J. Anal.

Figure 10. Mg -excited ESCA spectra of some lead compound mixtures, acquired in the region of the kinetic energy corresponding to the Pb 4f (4f5/2 and 4f7/2> peak-doublet transitions. The lack of collinearity among the compcsients and mixtures makes the Kalman filter separation not feasible, (a) Pb02+PbS04 (60 40) (b) Pb02+Pb(C03> (60 40) (c) Pb02+Pb(N03)2+Pb(C03) (35 35 30), (d) Pb02++Pb(C03)+Pb(S04) (20 20 60) (c) pure Pb(C03) (f) pure Pb(S04). (From Fresenius J Anal. Chem (1993) 345 490, with permissirai).

Comparison of the Kalman filter resolution of the ESCA spectra of some binary and ternary lead compound mixtures after search for the optimal alignment by simplex, steepest descent and simulated annealing. Nr is the number of iterations of the optimisation until convergence n.c. no convergence.(From Fresenius J Anal. Chem (1993) 345 490, with permission).
