Abstract
The vibration-rotation spectrum of PH and the $A^{2}\Pi-X^{2}\Sigma^{+}$ electronic transition of CP were recorded in the infrared with the Fourier transform spectrometer associated with the McMath Solar Telescope at Kitt Peak. CP and PH were made in a microwave discharge of $P_{4}$ vapor and $H_{2}$. The carbon required to make CP was present as a deposit on the discharge tube walls. The 1-0, 2-1 and 3-2 and 4-3 vibration-rotation bands of the $X^{3}\Sigma^{-}$ state of PH were observed and molecular constants extracted. For CP the 0-0, 1-0, 3-1, 0-1, 0-2 bands of the $A^{2}\Pi-X^{2}\Sigma^{+}$ transition were observed from $4000-8600cm^{-1}$. The A-X transition of CP is analogous to the red system of CN.
