The spectral line profiles of n=4 to 3 transitions emitted by the Li-like ions of carbon and nitrogen in a hot, dense hydrogen plasma are calculated and compared to measurements. The excellent agreement with the independently measured temperature and density establishes the theoretical model and validates its use as a plasma diagnostic. The effect of spectral resolution on the accuracy of the determination of the plasma conditions is examined.
