N2 - The bands ν5, ν6 + ν8, ν7 + ν8, ν6 + ν9, and ν8 of NCCCCN have been investigated in the gas phase with a resolution of 0.003 cm-1. The ground state rotational constants B0 = 0.04458699(10) cm-1 and D0 = 1.049(4) × 10-9 cm-1 have been determined, together with the constants and the vibrational frequencies for the above bands. Several hot bands from the v9 = 1 state were analyzed to give B9 = 0.04468316(18) cm-1, D9 = 1.117(5) × 10-9 cm-1, q9 = 3.85(2) × 10-5 cm-1, and q9J = 2.4(7) × 10-11 cm-1. The bond lengths of NCCCCN correspond very closely to those of HCCCCCN.
