Data from the Kitt Peak National Observatory (KPNO) coudé feed telescope were used to analyze the strength of three well-known diffuse interstellar bands (DIBs; 5780, 5797, and 6614 Å). Ten mid-A, mid-F, and mid-G stars with moderate reddening (E_B–V=0.2-1.2) were observed, along with one reddened B0 dwarf for comparison. Synthetic spectra were calculated to remove the interference of stellar features. We report the detection of all three DIBs in A, F, and G stars. We also find the correlation of DIB strengths with E(B-V), in our sight lines, to be consistent with previous results from Herbig ((ref???)1993), demonstrating that DIB strength is not dependent on the spectral type of the target star.
