摘要：

Shifts in spectral line positions of argon, iron, barium, calcium and strontium are addressed in this preliminary study of the effect of pressure, and electron density on wavenumber position in the 27.12 MHz inductively coupled plasma (ICP). We report line shifts for three sets of data in an argon ICP. The first set of data shows the effect of power (1.1, 1.5, 1.9 kW) on shifts of argon (21 lines) and iron (28 lines) lines in the ultraviolet and visible. The second set of data gives shifts of 25 Ar lines in the near infrared (i.r.) and far visible at 1.1 kW. The third set of data concerns prominent ion lines of calcium, barium and strontium. Commercial hollow cathode lamps (HCL) were used to obtain unshifted line positions. The Los Alamos Fourier Transform Spectrometer was used to obtain the data. © 1990.
