将加热的乙醛酸样与室温甲酸在氩气中混合,制得气相双氢键合乙醛酸-甲酸氢键络合物。用不同基组进行了高水平密度泛函理论和MP2计算,确定了乙醛酸-甲酸的最低能量二聚体的结构和转动常数。用两台Flygare-Balle型脉冲束傅里叶变换微波(FTMW)光谱仪测量了6-12 GHz频率范围内的微波频谱。用18个跃迁测得的转动常数值如下:A=5533.911(3),B=923.3883(5),C=792.1132(6)MHz。对最低能量二聚体的B3LYP/cc-pVQZ计算得到的转动常数分别为A=5551.2,B=922.9和C=791.3兆赫。
The gas-phase doubly hydrogen-bonded glyoxylic acid - formic acid hydrogen-bonded complex was obtained by mixing a heated sample of glyoxylic acid with room-temperature formic acid in argon. High-level DFT and MP2 calculations with various basis sets were performed and the structures and rotational constants were determined for the lowest energy dimers of glyoxylic acid - formic acid. The microwave spectrum was measured in the 6-12 GHz frequency range using two Flygare-Balle type pulsed beam Fourier transform microwave (FTMW) spectrometers. The rotational constants were determined to have the following values: A = 5533.911(3), B = 923.3883 (5), and C = 792.1132(6) MHz using 18 transitions. B3LYP/ cc-pVQZ calculations for the lowest energy dimer yielded calculated rotational constants of A = 5551.2, B = 922.9 and C = 791.3 MHz.
