采用低温22极离子阱中激光诱导反应的方法记录了基态(X(2)Pi(u))C(2)H(2)(+)的nu(5)顺式弯曲振动的光谱。它是通过计算反应产物的数量 C(2)H(2)(+) (v(5) = 1) + H(2)--> C(2)H(3)(+) + H 作为激光波长的函数而获得的。已经观察到振动电子跃迁 Delta-Pi 和 Sigma-Pi 及其相应的自旋轨道和 Renner-Teller 子结构。通过微扰分析，振动频率确定为 omega(5) = (710 +/- 4) cm(-1)，Renner-Teller 参数 epsilon(5) 约为 3 x 10(-2)。
The spectrum of the nu(5) cis-bending vibration of ground state (X(2)Pi(u)) C(2)H(2)(+) has been recorded applying the method of laser induced reactions in a low-temperature 22-pole ion trap. It is obtained by counting the number of products of the reaction C(2)H(2)(+) (v(5) = 1) + H(2)--> C(2)H(3)(+) + H as a function of the laser wavelength. The vibronic transitions Delta-Pi and Sigma-Pi with their corresponding spin-orbit and Renner-Teller substructure have been observed. Using a perturbative analysis, the vibrational frequency has been determined to omega(5) = (710 +/- 4) cm(-1) and the Renner-Teller parameter epsilon(5) is on the order of 3 x 10(-2).
