Commentary
Short इ is optionally substituted for the penultimate vowel of the Causative अङ्ग (stem) of घ्रा in the Aorist.
As अजिघ्रिपत् or अजिघ्रपत्, अजिघ्रिपताम् or अजिघ्रपताम्, अजिघ्रिपम् or अजिघ्रपम् ॥ Thus घ्रा + णि + अत् = घ्राप् + इ + अत् 7.3.36 = घ्रिप् + इ + अत् 7.4.6 = घ्रिप् + अत् 6.4.51 = जिघ्रिपत् ॥ When इ is not substituted, आ is shortened by 7.4.1.
