The rotational spectrum of dimethylether-hydrogen chloride (see Fig. below) has been assigned and measured by millimetre wave free jet absorption spectroscopy. The HCl moiety is delocalised between the two lone pairs of the ether oxygen, as shown by the wide splitting, 8186(7) MHz, between the two tunnelling components of the ground state. The corresponding barrier to the transfer of HCl from one lone pair to the other one has been evaluated from the experimental data to be 55 cm-1.

Abstract
The rotational spectrum of dimethylether-hydrogen chloride (see Fig. below) has been assigned and measured by millimetre wave free jet absorption spectroscopy. The HCl moiety is delocalised between the two lone pairs of the ether oxygen, as shown by the wide splitting, 8186(7) MHz, between the two tunnelling components of the ground state. The corresponding barrier to the transfer of HCl from one lone pair to the other one has been evaluated from the experimental data to be 55 cm-1.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
