I understand that both かと思うか and 途端に mean "as soon as something happen another
thing happens as well". I see that their usage is different, especially when
かと思うか is used with emotive verbs, however I still feel that I don't understand
the difference. Maybe,it might be that I didn't fully understand かと思うか. Can
somebody help me out?

What's the difference between かと思うか and 途端に?
I think 「かと思うか」is not an established phrase, but 「思う」is often used with
[「が[早]{はや}いか」or「や[否]{いな}や」](https://japanese.stackexchange.com/questions/4916/%E3%81%8C%E6%97%A9%E3%81%84%E3%81%8B-versus-%E3%82%84%E5%90%A6%E3%82%84?rq=1)
.  
「...[思]{おも}うが[早]{はや}いか」 (meaning as soon as I thought something) indicates
virtually the same thing as 「思った[途端]{とたん}に」. So it might
be「[思]{おも}うが[早]{はや}いか」that you had in mind. The example sentence in your
comment:  
[最近]{さいきん}は[肌寒]{はだざむ}くなったかと[思]{おも}うと[翌日]{よくじつ}には[暖]{あたた}かくなったりする。  
is about another topic. The particle 「と」 in 「思うと」 is a conjunctive particle
and is working like "whenever" in English.  
The 「と」 indicates one thing always follow the other thing ,and this sequence
of events occurs repeatedly. It is combining with other words to suggest a
sense of immediacy but not exactly working like "as soon as" by itself.
