加压后，Ph2HP中的1JP-H显著增加，而PH213CH2中的1J13C-H几乎不受影响。磷孤对电子与氯仿之间氢键作用的增强被认为是压力诱导1JP-H变化的原因。
Upon pressurization, 1JP-H in Ph2HP has been found to increase notably, while 1J13C-H in Ph2 13CH2 has been observed to remain nearly unaffected. An increased hydrogen bonding interaction between phosphorus lone pair electrons and chloroform is considered to be responsible to the pressure induced change in 1JP-H.
