Comprehensive spectroscopic studies of hot and ultracold samples of NaCs molecules were combined to complete the investigation of the (3){Omega}=1 <- X {sup 1}{Sigma}{sup +} transition for the NaCs molecule. Polarization labeling, photoassociation, and pulsed laser depletion spectroscopy were used to collect data on rovibrational levels of the (3){Omega}=1 state [here described as the c {sup 3}{Sigma}{sup +} state in Hund's case (a) notation]. The highest observed level was v=72 located {approx}5 GHz below the atomic asymptote Na(3 {sup 2}S{sub 1/2}) + Cs(6 {sup 2}P{sub 3/2}). Approximately 1400 levels were used to construct the potential energy curve of the (3){Omega}=1 state for the full range of interatomic distances.
