In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Measurements of structural and quadrupole coupling parameters for bromoferrocene using microwave spectroscopy, published in 1997-11-01, which mentions a compound: 1273-73-0, mainly applied to ferrocene bromo microwave spectroscopy; quadrupole coupling bromoferrocene; rotational spectra bromoferrocene; mol structure bromoferrocene, SDS of cas: 1273-73-0.
Rotational spectra for two isotopomers of bromoferrocene were measured using pulsed-beam Fourier transform microwave spectroscopy. Transitions were observed for the 79Br and 81Br isotopomers in the 5-9 GHz range. Rotational constants and the quadrupole coupling tensors were obtained. The rotational constants and quadrupole coupling parameters for 79Br are A = 1272.110(1), B = 516.1125(2), C = 441.3775(2), eQqaa=267.16(3), eQqab=-409.81(4), and eQqbb=21.49(4), and those for 81Br are A = 1271.045(4), B = 510.0079(2), C = 436.7687(2), eQqaa=225.40(6), eQqab=-341.62(4), and eQqbb=15.65(4). The measured rotational constants were used to determine the following structural parameters of bromoferrocene: r(Fe-(C5H5))=1.63(2), r(Fe-(C5H4Br))=1.67(3), r(C-Br)=1.875(11), and r(C-C)=1.433(1) A. The values of the quadrupole coupling parameters in the principal quadrupole axis systems and the C-Br bond axis systems are compared with similarly derived parameters for chloroferrocene, chlorobenzene, and bromobenzene. Previous data for chloroferrocene was reanalyzed to obtain refined quadrupole parameters.
