	abstract = {The influence of the ratio of the rod radius, r, to field radius, r(0), on the peak shape for a linear quadrupole mass filter constructed with round rods has been investigated. The expansion of the potential in multipoles, phi(N),Phi(x,y)= Sigma(N=0)(infinity)A(N)phi(N)/r(0)(N), has been considered, and the peak shape and resolution have been determined by numerical calculation of ion trajectories in quadrupoles with different ratios, r/r(0). Geometries that make the dodecapole term (A(6)) zero (r/(0) = 1.14511) do not give the best performance because the contribution of the 20-pole term, A(10), must be considered. The optimum ratio is r/r(0) approximate to 1.13. With this ratio the dodecapole term (A(6)) is ca. 1 x 10(-3), but its effects are partially compensated by the A(10) term which has similar magnitude, but opposite sign.

	abstract = {The theory of the computer calculation of the stability of ion motion in periodic quadrupole fields is considered. A matrix approach for the numerical solution of the Hill equation and examples of calculations of stability diagrams are described. The advantage of this method is that it can be used for any periodic waveform. The stability diagrams with periodic rectangular waveform voltages are calculated with this approach. Calculations of the conventional stability diagram of the 3-D ion trap and the first six regions of stability of a mass filter with this method are presented. The stability of the ion motion for the case of a trapping voltage with two or more frequencies is also discussed. It is shown that quadrupole excitation with the rational angular frequency omega = NOmega/P (where N, P are integers and Omega is the angular frequency of the trapping field) leads to splitting of the stability diagram along iso-P lines. Each stable region of the unperturbed diagram splits into P stable bands. The widths of the unstable resonance lines depend on the amplitude of the auxiliary voltage and the frequency. With a low auxiliary frequency splitting of the stability diagram is greater near the boundaries of the unperturbed diagram. It is also shown that amplitude modulation of the trapping RF voltage by an auxiliary signal is equivalent to quadrupole excitation with three frequencies. The effect of modulation by a rational frequency is similar to the case of quadrupole excitation, although splitting of the stability diagram differs to some extent. The methods and results of these calculations will be useful for studies of higher stability regions, resonant excitation, and non-sinusoidal trapping voltages.

	abstract = {Laser excitation of isotopically labeled SO2 molecules in a neon matrix has allowed the measurement of dispersed phosphorescence spectra ((a) over tilde(3)B(1)-(X) over tilde(1)A(1)) in the wavelength region 387.5-526.3 nm (19 000-25 800 cm(-1)). The origin of the (a) over tilde-(X) over tilde transition lies at 25 747 cm(-1) in (OSO)-O-16-O-16, shifted 18 cm(-1) to the red from the gas phase; the three vibrational frequencies of the (X) over tilde state are nearly unperturbed in the neon matrix (1149, 520, and 1362 cm(-1)). As the zero-phonon lines are sharp and well resolved, it has been possible to monitor emission from a specific isotopomer to obtain its excitation spectrum. The excitation spectra of matrix-isolated (OSO)-O-16-O-16 and (OSO)-O-18-O-18 in the region 350.9-388.5 nm (25 740-28 500 cm(-1)) are similar to those previously observed in the gas phase, with strong perturbations affecting all vibrational levels above a(3)B(1)(110) at 27 005 cm(-1) (370 nm). Two additional groups of bands are observed for the unsymmetrical isotopomer (OSO)-O-18-O-16; they are identified as transitions to levels of the (a) over tilde(3)B(1) state with v(3) = 1 and as direct transitions to the (b) over tilde(3)A(2) state, which both become allowed in the lower symmetry. The v(3) frequency of the (a) over tilde(3)B(1) state of (OSO)-O-18-O-16 is 922 cm(-1); for the (b) over tilde(3)A(2) state, v(1) similar or equal to 791 cm(-1) and v(2) similar or equal to 315 cm(-1), while the (b) over tilde (001) level lies 26 653 cm(-1) above the (X) over tilde (000) level.},

Thus, an intra-molecular property, diamagnetic susceptibility, is not completely free from the effect of a non-ideal molecular arrangement in the mixture.},
