(1) The A(010)^3SIGMA^<(-)> - X^3SIGMA^-(000), A(010)^3SIGMA^<(-)> - X^3SIGMA^-(010) and A(010)^3SIGMA^<(+)> - X^3SIGMA^-(010) bands in the A^3PI_i - X^3SIGMA^- system of the CCO radical have been investigated by means of near-infrared high-resolution diode laser spectroscpy. The spectra have been analyzed to determine detailed molecular constants for both the X^3SIGMA^-(010) and A^3PI_i(010) states including a Renner parameter. Numerous perturbed levels have been found in the A(010)^3SIGMA^<(+)>_0 and A(010)^3SIGMA^<(+)>_1 states.(2) The A^2PI_<3/2>, v=3 <- X^2SIGMA^+, V=0 band of the AlO radical has been sudied by means of near-infrared diode laser spectroscopy in the region from 7470 cm^<-1> to 7490 cm^<-1>. The spectrum has been analyzed to determine newly molecular constants for the A^2PI_<3/2>, v=3 state.

(1)用近红外高分辨半导体激光光谱分析方法研究了CCO自由基的A(010)^3SIGMA^&lt；(-)&gt；-X^3SIGMA^-(000)，A(010)^3SIGMA^&lt；(-)&gt；-X(010)^3SIGMA^-(010)和A(010)^3SIGMA^&lt；(+)&gt；-X^3PI_I-X^3SIGMA^-(010)谱带。对光谱进行了分析，确定了X^3SIGMA^-(010)和A^3PI_I(010)态的详细分子常数，包括Renner参数。在A(010)^3SIGMA^&lt；(+)&gt；_0和A(010)^3SIGMA^&lt；(+)&gt；_1态中发现了大量的微扰能级。(2)在7470 cm^&lt；-1&gt；-7490 cm^&lt；-1&gt；-X^2SIGMA^+，V=0范围内，用近红外激光光谱研究了AlO自由基的A^2pi_&lt；3/2&gt；，-X^2SIGMA^+，V=0带。对光谱进行了分析，确定了新的A^2pi&lt；3/2&gt；，v=3态的分子常数。
