摘要: A Stark modulation-type spectrograph has been constructed. Millimeter wave klystrons are used as the power source. The sensitivity of is about 2×10 -7 cm -1 at 70 Gc, when spectral lines displayed on a cathode-ray oscilloscope with sweep rate 1 cps. R -branch transitions 01 ←0 00 formaldehyde isotopic species H 2 C 13 O, CO 18 , HDCO, D CO, O and have measured their rotational constants determined. observed inertia defects shown to be in good agreement predicted theoretical values. From r z -structures determined
