Ten bands with $0\leq v^{\prime}\leq 2$ and $6\leq v^{\prime\prime}\leq 9$ of $I^{35}C1$ were recorded photoelectrically in the range $\lambda 8000-9800$ \AA, and were analysed to provide the first reliable rotational constants and terra values for these levels. The A $\leftarrow$ X system in absorption was photographed at high resolution using a 3.5 m Ebert spectrograph in the range$\lambda 7000-8000$ \AA. Sixteen bands of $I^{35}C1$ with $3\leq v^{\prime}\leq 8$ and $2\leq v^{\prime\prime}\leq 5$ were analyzed. The present data and those obtained by refitting the precisely measured wavenumbers from the absorption spectrum at shorter $wavelengths^{1}$ were $merged^{2}$ to provide a self-consistent and extensive set of molecular constants for both the $A^{3}\Pi(1)$ and $X^{1}\Sigma^{+}$ states. The RKR turning points for these states and the Franck-Condon factors for the A - X system have been calculated. en_US dc.format.extent 145973 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title ROTATIONAL ANALYSIS OF THE $A^{3}\Pi(1)-X^{1}\Sigma^{+}$ SYSTEM OF IC1 IN EMISSION AND IN ABSORPTION en_US dc.type article en_US
