I.r. intensities of series of meta-substituted benzenethiols and methyl phenyl and phenyl t-butyl sulphides confirm the following order of resonance donation: SMe > SH SBut. The intensities of the para-substituted benzenethiols and phenyl sulphides are interpreted in terms of sulphur d-orbital acceptance when the divalent sulphur opposes a donor substituent. A scale of d-orbital-acceptor ability is
一系列间位取代的苯硫醇与甲基苯基和苯基叔丁基硫化物的Ir强度证实了共振给予的以下顺序:SMe> SH SBu t。当二价硫与供体取代基相对时,对位取代的苯硫醇和苯硫醚的强度用硫d-轨道接受来解释。对于一系列取代基,给出了d-轨道受体能力的规模。
