Hello:

I apologize for the trivial nature of this question,
but an extensive STN search found nothing.

I am looking for the average bond length in
the polymethine chain in several cyanine dye series.

The compounds are:

3,3'-diethyloxacarbocyanine (di- and tri- carbocyanine as well) iodide

and

1,1'-diethylcarbocyanine (di- and tri- crbocyanine as well) iodide

A computer calculated value or a resource would be great.
Thank you for your time.
You effort is appreciated by my professor and by myself.
