Abstract
Rotational transitions for acetylene-HCl were measured in magnetic fields of 28 and 30 kG using a pulsed-nozzle, Fourier transform microwave spectrometer. Measured molecular g values are gaa = 0.0519 (5), gbb = -0.0006 (2), and gcc-0.0025 (2). Susceptibility anisotropies are 2Xaa-Xbb-Xcc = 0.08 (4) X 10-9 and 2Xbb-Xcc -Xaa = -1.14 (8) X 10-9 MHz/G2. Molecular quadrupole moments for the complex are Qaa = -2.6 (3), Qbb = 6.2 (3), and Qcc = -3.7 (3) X 10-26 esu cm2. We find that the molecular g value for acetylene is positive, g = 0.044 (1). The molecular quadrupole moment of acetylene is found to be 8.0 (16) X 10-26 esu cm2 in good agreement with calculated values.
