合成了一种双取代15n甲酸甲醛样品,并利用flygre - balle型脉冲束傅里叶变换微波(MW)光谱仪在5.6 ~ 14.2 GHz频率范围内测量了样品的微波光谱。测量并拟合了13个A型旋转跃迁,得到了15n取代同位素物的旋转常数和离心畸变常数。测定的旋转常数和离心畸变常数有以下值:A = 5808.02(18) MHz, B = 2127.008(2) MHz, C = 1557.615(2) MHz, DJ= 0.60(11) kHz, DJK= 4.95(71) kHz, DK= - 0.138(24) kHz。他们搜索了隧道裂缝,但没有发现。该化合物的核磁共振谱包括δC、δN、1JCH、1JCNand2JNHin、CD3SOCD3、CD3OD和D2O的值。D2O中NH - ND交换的发生使得偶然的jnd测量成为可能。
A sample of doubly-substituted15N formamidinium formate was synthesized and the microwave spectrum was measured in the 5.6–14.2 GHz frequency range using a Flygare-Balle type pulsed beam Fourier transform microwave (MW) spectrometer. A total of 13 a-type rotational transitions were measured and fitted to obtain the rotational constants and centrifugal distortion constants for the15N substituted isotopologue. The rotational constants and centrifugal distortion constants determined have the following values: A = 5808.02(18) MHz, B = 2127.008(2) MHz, C = 1557.615(2) MHz, DJ= 0.60(11) kHz, DJK= 4.95(71) kHz and DK= −0.138(24) kHz. Tunneling splittings were searched for, but not observed. NMR spectra for this compound are reported including values of δC, δN,1JCH,1JCNand2JNHin CD3SOCD3, CD3OD and D2O. The occurrence of NH to ND exchange in D2O allowed the fortuitous measurement of1JND.
