The millimeter-wave rotational spectra of the ground and excited vibrational states v7 =1 and v8 =1 of the symmetric top molecule, CCl3CN, have been analyzed again. The B0 = 1666.80894(13) MHz, DJ = 0.135023 (23) kHz, DJK = 0.60596 (45) kHz, HJ = -0.0192 (10) mHz, HJK = 1.188 (34) mHz and HKJ = -1.60 (21) mHz have been determined for ground state. The 𝓁 = ±1 series have been assigned and the rotational parameters including B7 =1667.96659(25) MHz, (q+t)7=1.58855(94) MHz for v7 =1 and B8 =1667.08204 (31) MHz, (q+t)8 = 1.6141(36) MHz for v8 = 1 states were determined accurately.
