today, while working on my thesis (on occasionalisms in the poetry of Marina Cvetaeva), I stumbled upon something strange.
My theoretical grammar tells me that a secondary imperfective might sometimes involve an accented 'o' in the stem to be changed into a an accented 'a' (for example: вздрóгнуть --> вздрáгивать). However, I noticed that sometimes this 'o' doesn't need to be accented in order to change upon secondary imperfectivation (for example: всмотрéться --> всмáтриваться). This is also reflected in Cvetaeva's use of secondary imperfectivation (for example, she uses горéть to create погáрывать). She does this consistently; it is not an one time occurence.
So I wonder, is there perhaps another rule? Or is the rule that my grammar book supplies just narrow? I tried finding some articles on the matter, but it's like looking for a needle in a haystack.
Thanks in advance,

Sorry, your question was in the spam folder.
Yes, the rule is quite narrow. In fact, I think there are no rules for accents in this case. Please, note than Tsvetaeva's second imperfectivation is quite particular, the verbs she uses are never used in the Russian language.
