摘要:

利用低温离子阱装置和作用光谱法首次观察到了$^{12}$ C $^{14}$ N $^+$和$^{12}$ C $^{15}$ N $^+$阳离子的基振动模的转动-振动跃迁。测量了$^{12}$ C $^{14}$ N $^+$的谱线P(3)至R(3)和$^{12}$ C $^{15}$ N $^+$的谱线R(1)至R(3),这受到约4 K的陷阱温度和有限的红外激光调谐范围的限制。给出了两种同位素体的光谱参数,谱带起源分别为2000.7587(1)和1970.321(1)cm $^{-1}$,以及结合新数据和文献数据的同位素独立拟合。

英文摘要:

Rotational-vibrational transitions of the fundamental vibrational modes of the $^{12}$C$^{14}$N$^+$ and $^{12}$C$^{15}$N$^+$ cations have been observed for the first time using a cryogenic ion trap apparatus with an action spectroscopy scheme. The lines P(3) to R(3) of $^{12}$C$^{14}$N$^+$ and R(1) to R(3) of $^{12}$C$^{15}$N$^+$ have been measured, limited by the trap temperature of approximately 4 K and the restricted tuning range of the infrared laser. Spectroscopic parameters are presented for both isotopologues, with band origins at 2000.7587(1) and 1970.321(1) cm$^{-1}$, respectively, as well as an isotope independent fit combining the new and the literature data.
