@NMRspectroscopy There will be a doublet in B (the proton next to nitrogen) which will come at more than 8 or 8.1 ppm (certainly at ppm more than any of the proton positions in A). So, the NMR spectra consisting of the higher ppm proton (more de-shielded) will be the spectra of B

Vidisha is India’s latest ‘Lethal Weapon’ A soft-spoken bureaucrat who nullified the impact of a nuclear-armed, sabre-rattling challenger. We didn’t even need our PM, Foreign Minister or MEA Secretary to step into the ring.

The communication isn’t lost. Every single person in India can feel the heartbeat of #chandrayaan2 We can hear it whisper to us that ‘If at first you don’t succeed, try, try again.’

[Subramanian Swamy @Swamy39]

Despite the last minute glitch, the ISRO performance was magnificent. Every grand effort of our scientists is praise worthy. No great achievement happens without early setbacks.

[ANI @ANI]

PM Narendra Modi: There will be a new dawn and a brighter tomorrow very soon. There is no failure in science, only experiment and efforts #Chandrayaan2

[Rahul Kanwal @rahulkanwal]

Proud of every scientist and engineer at @isro You fired the imagination of a billion Indians. May the lessons you learn from Chandrayaan 2 propel you to greater heights in the years to come.

No. Such. Thing. As. Failure. In. Science. And. Exploration.

@TarekFatah Listen to #ArundhatiRoy . Never knew she was so uneducated and unread. Pak has killed thousands of its own in FATA, Baluchistan and Waziristan. Yet she claims Pak has never deployed its army against its own. Where do such uninformed anti-nationals come from. Need to be shamed

[Israel Defense Forces @IDF]

These IDF soldiers were born in India and they have a special message in honor of #IndiaIndependenceDay

[Syed Ata Hasnain @atahasnain53]

Happy Independence Day to all. Can't help but compare PM Modi's Independence Day speech with the speech of the Pakistan PM.
So much said, almost every facet of functioning covered. For me three biggest takeaways, Ease of Living, Jal Jiwan Mission, CDS above three Services

[Syed Ata Hasnain @atahasnain53]

Congratulations to all award winners from one of the OG fraternity. Proud if you guys

[Syed Ata Hasnain @atahasnain53]

Before PM Modi who is too far above your pay band, do come and debate with me on J&K. We will start by declaring how much time each of us have spent there understanding the grassroots to the strategic level.
