The emission spectrum of the Ångström system (B^1Σ^+ → A^1Π) of ^{13}C^{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^{-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_v, D_v for the B^1Σ^+ and A^1Π states; (2) the equilibrium constants B_e,α_e, D_e, andβ_e for the B^1Σ^+ state; (3) theν_0 band origins. A combined analysis of the currently observedÅ ngström bands and the previously observed Herzberg (C^1Σ^+ → A^1Π) and the (E^1 Π → A^1Π) bands made it possible to perform a precise relative characteristic of the B^1 Σ^+(v=0 and 1), C^1Σ^+(v=0) and E^1Π(v=0) Rydberg levels in ^{13}C^{16}O. Numerous rotational perturbations observed in the A^1 Π state were confronted with the perturbations predicted from the theoretical calculations.
