What What about about CH CH22I<br />

I ??? ???<br />

Difficultiies<br />

Difficult es with with producing and and<br />

detecting<br />

No experimental data <strong>of</strong> rotational rotational<br />

constants constant<br />

How ow to produce ?<br />

CH3Br CH Br + Cl → CH2Br CH Br ...exotherm<br />

... exothermic ic reaction<br />

CH3I CH I + Cl → CH2I CH I ...exo ... exo, , endo... endo...<br />

Not clear<br />

according to papers<br />

Fine and hyperfine splitting: splitting:<br />

II I (5/2)>IBr (5/2)>IBr(3/2)<br />

(3/2)<br />

Lines ines <strong>of</strong> CH 2I I are expected weaker than lines<br />

<strong>of</strong> CH2Br CH Br:<br />

= 0,8 < µ (CH2Br ) = 1<br />

: µ( ( CH2I ) =<br />

< µ(CH2Br )
