Form of Russian adverbs

Question

Does the short neuter form of adjectives always automatically constitute the corresponding adverb, or are there cases of the short neuter form and the adverb having different forms/stress patterns?

Answer 1

Равный yields the short neuter равнó but the adverb is рáвно. I think there are other adverbs that don't follow suit when the corresponding short adjective shifts stress to the last syllable.

Then, most passive participles with the suffix -нн- lose the second н in the short form, while the adverb keeps it geminated: растерянный — общество растеряно, but растерянно улыбнуться. That can also be accompanied by a non-matching stress shift: определенó (adj.) vs. определённо (adv.)
