- Opis:
- The emission spectrum of the Ångström system (B$\text{}^{1}$Σ$\text{}^{+}$ → A$\text{}^{1}$Π) of $\text{}^{13}$C$\text{}^{16}$O was recorded and analysed by classical photographical spectroscopy. Under high resolution and with a precision estimated to be 0.010-0.020 cm$\text{}^{-1}$ the bands 1-2, 1-7, and 0-6 were recorded for the first time and the 0-1, 0-2, 1-1, and 1-5 bands were rephotographed and reexaminated. After the rotational analysis of the bands the following constants were calculated: (1) the rotational constants B$\text{}_{v}$, D$\text{}_{v}$ for the B$\text{}^{1}$Σ$\text{}^{+}$ and A$\text{}^{1}$Π states; (2) the equilibrium constants B$\text{}_{e}$,α$\text{}_{e}$, D$\text{}_{e}$, andβ$\text{}_{e}$ for the B$\text{}^{1}$Σ$\text{}^{+}$ state; (3) theν$\text{}_{0}$ band origins. A combined analysis of the currently observedÅ ngström bands and the previously observed Herzberg (C$\text{}^{1}$Σ$\text{}^{+}$ → A$\text{}^{1}$Π) and the (E$\text{}^{1}$ Π → A$\text{}^{1}$Π) bands made it possible to perform a precise relative characteristic of the B$\text{}^{1}$ Σ$\text{}^{+}$(v=0 and 1), C$\text{}^{1}$Σ$\text{}^{+}$(v=0) and E$\text{}^{1}$Π(v=0) Rydberg levels in $\text{}^{13}$C$\text{}^{16}$O. Numerous rotational perturbations observed in the A$\text{}^{1}$ Π state were confronted with the perturbations predicted from the theoretical calculations.
