2008年9月3日 · New values of the indirect spin–spin coupling constants in CH 4, SiH 4 and GeH 4, derived from experiment and ab initio calculations, are reported. The new experimental values of 1J (CH), 1J (SiH) and 1J (GeH) are obtained from gas-phase NMR spectra.

2014年12月16日 · X-ray diffraction studies demonstrate that oxidative addition of SiH4 to Ir(PPh3)2(CO)Cl yields Ir(PPh3)2(CO)(Cl)(SiH3)H, which features a cis arrangement of the SiH3 and H ligands in which H is located trans to CO, rather than trans to Cl as originally reported. 1H NMR spectroscopic studies indicate that ox

The 'H NMR spectrum of tetrahedral GeH4 is shown below. The spectrum has been amplified and the large central line is cut off. There are 10 smaller lines, 5 on either side of the large central peak.

H NMR spectroscopic studies indicate that oxidative addition of GeH(4) to Ir(PPh(3))(2)(CO)Cl also occurs in a cis manner but results in the formation of two isomers of Ir( PPh( 3))( 2)(CO)(Cl)(GeH(3)))H, which are related by H being trans to either CO or Cl.

2015年2月14日 · X-ray diffraction studies demonstrate that oxidative addition of SiH(4) to Ir(PPh(3))(2)(CO)Cl yields Ir(PPh(3))(2)(CO)(Cl)(SiH(3))H, which features a cis arrangement of the SiH(3) and H ligands in which H is located trans to CO, rather than trans to Cl as originally reported.
