Experimental studies of the broadening of the absorption line J = 6 ⇒ 7 of (CH_{3})_{3}CCN due to collisions with the foreign perturbers He, CO_{2}, OCS, and CH_{3}CN have been carried out. The magnitude of the broadening coefficients reflects the type of interactions occurring in the molecular collisions. It has been concluded that the dipole-dipole and dipole-quadrupole interactions are predominant in the (CH_{3})_{3}CCN admixed with CH_{3}CN and OCS. In the collisions between (CH_{3})_{3}CCN and CO_{2} the dipole-quadrupole interactions are present whereas the He perturbed by (CH_{3})_{3}CCN exhibits dispersive type of interactions.
