✦ Synopsis

Rotational analyses of the B 2 ⌺ u ϩ 3 X 2 ⌺ g ϩ system of the 14 N 2 ϩ molecule have been extended to include the vibrational levels up to vЈ ϭ 4. Spectral data from 20 bands obtained from high-resolution Fourier transform spectrometry of a hollow-cathode and a Pointolite lamp were included in the analysis. A global deperturbation yielded molecular parameters of the highly perturbed B 2 ⌺ state and interaction parameters A 2 ⌸ u ϳ B 2 ⌺ u with a standard deviation of 0.011 cm Ϫ1 . Rotational term values of the B 2 ⌺ ϩ state were also determined. New perturbations in the B 2 ⌺ ϩ (v ϭ 0) level have been observed at N ϳ 85 and N ϳ 96.

The Fourier transform Raman spectra of the fundamental bands of 14 N 15 N and 15 N 2 were measured with a resolution of 0.02 cm -1 . Lines from all branches (O, Q, S) were observed and measured. The analyses of the wavenumbers yield improved values for the band origins n 0 . 14 N 15 N/ = 2291.33773.

It is well-known that mass resolving power in Fourier transform ion cyclotron resonance mass spectrometry (FTICR MS) can increase linearly with increasing applied magnetic field induction, B. Here, we show that eight other FTICR primary performance parameters theoretically also increase linearly (qu
