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 g//a//a equals 0. 0519 (5), g//b//b equals minus 0. 0006 (2), and g//c//c equals 0. 0025 (2). Susceptibility anisotropies are 2// CHI //a//a minus // CHI //b//b minus // CHI //c//c equals 0. 08 (4) multiplied by 10** minus **9 and 2// CHI //b//b minus // CHI //c//c minus // CHI //a//a equals minus 1. 14 (8) multiplied by 10** minus **9 MHz/G**2. Molecular quadrupole moments for the complex are Q//a//a equals minus 2. 6 (3), Q//b//b equals 6. 2 (3), and Q//c//c equals minus 3. 7 (3) multiplied by 10** minus **2**6 esu cm**2. The authors find that the molecular g value for acetylene is positive. The molecular quadrupole moment of acetylene is found to be 8. 0 (16) multiplied by 10** minus **2**6 esu cm**2 in good agreement with calculated values.
