Abstract
A new band system ascribed to the N+2 molecule has been observed in the 3820–3920 Å region from hydrogen ion bombardment of nitrogen molecules. Particle energies up to 30 keV were displayed, at typical target pressures of 10−3–10−2 torr. Beam currents as high as 25 μA have been measured. The emission proceeds from a 4Σ+u→X 2Σ+g transition. Rotational analysis of the (0,0) and (1,1) bands leads to the following molecular constants derived by least‐squares technique: Te=25 467 cm−1, ωe=2398 cm−1, ωexe=14 cm−1, Be=2.071 cm−1, αe=0.014 cm−1, re=1.078 Å, ν00=25 563.26 cm−1, and 3ε=0.69 cm−1.Keywords
