The first assigned electronic gas phase spectrum of a magnesium chain species dates to 1996, when laser induced fluorescence studies reported the 2-2+ origin band of MgCCH. In subsequent investigations, the corresponding transitions due to MgC4H and MgC6H were obsd., but the MgC4D isotope has not been studied spectroscopically. The present study describes the line positions and a rotational anal. for the origin band of the 2-2+ transition of this mol. The results show an increase in the rotational const. of 24MgC4D, which reflects a decrease in the overall length of the chain upon electronic excitation.
