No. Dark Pulse is present in Black/White, but it is no longer a TM.
Some Pokemon that were able to learn Dark Pulse via TM may still do so by level-up or through breeding. You can find a list of those on Bulbapedia.
There is also a Dark Pulse move tutor in Black/White 2, who you can use to teach Dark Pulse to your Pokemon. This Pokemon could then be traded into Black/White 1. A list of compatible Pokemon is available on previously-linked Bublapedia page.
The move isn't a TM anymore in Pokemon Black and White and can only be learned by LVing up or by Breeding....

The move dark pulse is the last move on his list. Hoped this helped :-)
