| Popis: | The high resolution laser Stark spectra of methanol and13C-substituted methanol have been studied up to Stark fields of about 60 000V/cm with the HCN and DCN lasers. Numerous families of absorption lines have been observed in both parallel and perpendicular polarizations. For methanol, the transitions J k =75 ← 64 A,υt=0; J k =114 ← 103 E l ,υt=0; and J k =173 ← 162 E2,υt=0 have been identified while the assignments for13C-substituted methanol are J k =148 ← 157 A,υt=0; J k =153 ← 142 A+,υt=0; J k =107 ← 96 A,υt=0; and J k =279 ← 278 E1,υt=0. Zero-field frequencies for the assigned transitions are given with improved accuracy over those calculated from available molecular constants, especially for13CH3OH. |
