Image of FIG. 1.
FIG. 1.

Spectrally integrated, C2, and CN monochromatic images of graphite plasma at 0.4, 1, and 5 Torr N2 pressures. Each image is normalized to its maximum intensity for better clarity.

Image of FIG. 2.
FIG. 2.

Position–time (R-t) plots of the plume front at 0.4, 1, and 5 Torr nitrogen pressures measured from the spectrally integrated ICCD plume images. The symbols represent experimental data points and solid curves represent the drag expansion model.

Image of FIG. 3.
FIG. 3.

Space-time contours for C2 (λ = 516.5 nm) and CN (λ = 388.3 nm) in N2 gas at 0.4, 1, and 5 Torr pressure levels.

Image of FIG. 4.
FIG. 4.

Space-time contours for C (λ = 247.8 nm), C+ (λ = 426.7 nm), and C2+ (λ = 406.9 nm) in vacuum and N2 gas at 0.4, 1, and 5 Torr pressure levels.

Image of FIG. 5.
FIG. 5.

Position–time (R-t) plots for CN, C2, C, C+, and C2+ in vacuum and nitrogen at various pressures measured from the corresponding space-time contours. P1 and P2 refer to the early and delayed peaks, respectively, for the noticed double-peak structure of C and C+ in the presence of ambient nitrogen. The symbols represent experimental data points, dash lines represent linear fittings, and solid curves represent the drag expansion model.
