The scales of Kurinji are as follows :
Aarohanam (Ascending) : S N3 S R2 G3 M1 P D2
Avarohanam (Descending) : D2 P M1 G3 R2 S N3 S
Kurinji is a janya raga, derived from Dheera Shankharabharanam (below), 29th on the Melakarta scale.
It is a Dhavaitantya Raga with only limited sancharams as the highest note that can be sung or played in this Raga is the Dhaivatam (D2). This raga is sung within a single octave, giving a very mellow effect. It is therefore very suitable for lullabies as well as for aarati songs. Some well known songs in this raga are Seeta Kalyanam Vaibhogame by Tyagaraja, Bruhi Mukundenti by Sadashiva Brahmendra, Muddugare Yashoda and Ksheerabdhi Kanyakakku by Annamacharya. Annamacharya’s songs were discovered only as words; they have been set to music by other musicians.
Note : The 12 notes in the octave are named as below. Please note that C is used as Sa for the sake of simplicity as the scale is relative in Carnatic Music. Also note that the scales paint only a superficial picture of the raga as the gamakas(ornamentations) are a very important part of a raga.
Music To My Ears 
Just wondering- is the aarti song ‘jai ganesh jai ganesh’ also in kurinji perhaps? Can you please confirm.
This is certainly not Kurinji. If you want to know what are the signatures phrases of Kurinji, check out this site : http://www.ragasurabhi.com/carnatic-music/raga/raga–kurinji.html
Is this raga similar to Neelambari? How can we differentiate the two? Is Aliveni enthu cheyvu composed in Kurinji or Neelambari?
Sorry for the delayed response; I somehow missed your comment.
There are indeed similarities because the two ragas are janyas of the same Melakarta. But it is easy to differentiate between the two as they have very different ‘signature’ phrases. For raga recognition, Raga Surabhi is a good site which gives you small audio clips of the important phrases of each raga. Listen to the ‘signature’ of Kurinji here. http://www.ragasurabhi.com/carnatic-music/raga/raga–kurinji.html . Then listen to Sita Kalyana Vaibhogame or Ksheerabdi Kanyakaku (plenty of renditions in youtube) and see if you can spot the ‘signature’ phrases in them. And then do the same with Neelambari. http://www.ragasurabhi.com/carnatic-music/raga/raga–neelambari.html One easy hint for the distinction is that Kurinji doesn’t go into high notes. Aliveni Enthu Cheyvu is in Kurinji.

Sorry for the extremely delayed response! No, I am not familiar with Navarasam..don’t think I have ever heard it! Must look it up…
