Thanks! Just a few thoughts.

Well, after going here and yon on alkanes, hyposulfite compounds, haloalkanes, hyperfine structure, hyperfine constants, magnetic hyperfine fields and magnetic anisotropy fer Christ’s sake!

I’m satisfied that Iodine radicals are in fact stable due to their magnetic field.

I do have however a different perspective on a couple points.

1. The energy used for bond dissociation doesn’t necessarily translate into splitting AND making the Iodine magnetic.

You may therefore find that the Iodine radical is stable and may not even have a half life short enough to be bothered with.

2. To make people feel better and as an excellent sales point you should be able to find out the following using passive spectral analysis such as a spectrophotometer.

It can be easily proved if there is a half life (assuming its short).

There may be degradation back to I2 by heat or light. (You may find however this is not the case)

You might be able to wangle a free test of a Beckman instruments spectrophotometer.

Just have a newly made sample, a sitting on the shelf sample of 3 to 6 months.

Several samples exposed to light and known heat levels that might be encountered in shipping or storage.

The transition to I2 will give you additional absorption frequencies.

The light on these instruments “shouldn’t” affect the Iodine radicals.

If it does you’ll see the prime sample develop I2 absorption frequencies as it sits there.

Just a few thoughts.
