India were outplayed in all facets of the game during the pink-ball Test match.
Australia pulled off a thumping 10-wicket victory in the second Test at the Adelaide Oval to level the five-match series 1-1.
In the post-match press conference, Rohit attributed the loss to below-par batting but played down the impact of defeat.
“Firstly, it's not a (mental) scar, it's just we've lost a Test match. We didn't play well enough. So it's important in this short time that we have before the next Test match just to figure out certain things,” Rohit told reporters.
"You know, if you want to bat how we want to bat, and if you want to bowl, what lines and what lengths and what kind of fields placement we need to have.
"Those are the things more than anything else. Like I said, it's still one-all and plenty of things left in this series and definitely a way for us to get back into it."
India’s first innings folded for 180 while they were bowled out for 175 in the second dig, setting Australia a target of just 19 runs, which they chased down comfortably within the first session of Day 3.
"When you come to Australia I feel the best chance of winning a Test match is by putting runs on the board. And of course, when we won the toss, we elected to bat," said Rohit.
"We knew that there would be challenges. But in the past, where the conditions have been a little challenging, we've batted really well to put runs on the board and then try and put pressure on the opposition.
"That is the disappointing part, that we didn't bat well enough, you know, probably were 30-40 runs short with the bat in the first innings."
The visitors failed to make the most of the new pink ball when Australia batted during a crucial twilight phase on Day 1. While Jasprit Bumrah showed his brilliance, the rest of the bowling attack failed to deliver.
"There were opportunities when Australia were batting and we failed to take those chances," said Rohit.
"And obviously, when you miss those chances, it is never easy, the opposition will always make you pay for it, and that's what happened."
The third Test is scheduled to get underway on Saturday (December 14).
