-The results were obtained in the course of a line survey of the Galactic center source G 0.693–0.03 at 3 mm using the IRAM 30 m dish; additional observation around 1.3 cm were carried out with the GBT 100 m dish. The E-conformer was also identified. The Z/E ratio of about six indicated thermal equilibrium at the kinetic temperature of the cloud. The excitation temperature, in contrast, is rather cold, about 8 K.\\

+The results were obtained in the course of line surveys of the Galactic center source G 0.693–0.03 using the Yebes 40 m and IRAM 30 m telescopes. 14 //a//-type transitions with 2 ≤ //J// ≤ 10, //K<sub>a</sub>// ≤ 2 were identified between 31 and 107 GHz. Six of these transitions were unblended or only slightly blended. A non-thermal C-/N-cyanomethanimine ratio of ~32 was derived, while the //Z//-///E//-cyanomethanimine ratio of ~4.5 was deemed to be thermal, as may be expected for a pair of conformers. In contrast, N-cyanomethanimine is an isomer of C-cyanomethanimine, meaning, it requires the formal breaking of at least one bond for interconversion.\\
