I observed the Zeeman effect in a "transverse" and "longitudinal" configuration with a polariser and quarter wave plate -but I can't work out which component is polarised in each case!

It's been a while since I sat in a lab and did the Zeeman effect experiment. But seems to me transverse and longitudinal are relative terms. You pick one as transverse and the other becomes, by definition, the longitudinal simply because it is pi/2 out of orientation with the other.

Start with your polarized filters oriented for max intensity. Call that the transverse wave. Rotate one filter until you hit minimum intensity. Now rotate the other filter until the intensity maximizes again. That's the longitudinal portion...by definition. That second max should occur at the 3 o'clock position where the first max marks the 12 o'clock spot.

It's been forty plus years since I did the Zeeman thing; so take this answer with extreme caution.

I don't think you have the freedom to choose the directions of transverse and longitudinal. It is probably determined by the polarization of the incoming light.

hmmm.... I categorized that concept as " The Bush Syndrome " numerous years in the past... even with the reality that my Paper in this hypothesis became into in no way revealed... i've got faith it became into disregarded with the aid of fact of Bureaucratic Hypocritical Cronyism by utilising" the forged Ole Boys" interior the Elite international of technological know-how and Rightwing-nut Politics... yet, it somewhat is in basic terms MY Humble Opinion....!

No, it's a mystery.
