SF_6分子V_3带P、R支高分辨吸收光谱

High resolution absorption spectroscopy of the P and R branch of SF_6 in v_3 band

在四个全新频段内记录下SF_6分子吸收光谱,光谱分辨率达多普勒极限;所得108条谱线被分别归属为SF_6v_3振动带的P(29)～P(26)、P(39)～P(36)、R(20)～R(23)、R(334)～R(40).

In four new frequency bands, Doppler-limited absorption spectrum of v3 band of SF6 has been recorded and the quantum numbers (J values and octah edral symmetry types) of these recorded transitions have been assigned respectively to be P(29)-P(26); P(39)-P(36); R(20)-B(23); R(34)-R(40).
