Mopac has the following meanings:
MOPAC is a popular computer program used in computational chemistry. It is designed to implement semi-empirical quantum chemistry algorithms, and it runs on Windows, Mac, and Linux.
MOPAC2012 is the current version. MOPAC2009 is able to perform calculations on small molecules and enzymes using PM6, PM3, AM1, MNDO, and RM1. The Sparkle model (for lanthanide chemistry) is also available. This program is available in Windows, Linux, and Macintosh. Academic users can use this program for free, whereas government and commercial users must purchase the software.
MOPAC was largely written by Michael Dewar's research group at the University of Texas at Austin. Its name is derived from Molecular Orbital PACkage, and it is also a pun on the Mopac Expressway that runs around Austin.
MOPAC2007 included the new Sparkle/AM1, Sparkle/PM3, RM1 and PM6 models, with an increased emphasis on solid state capabilities. However, it does not have yet MINDO/3, PM5, analytical derivatives, the Tomasi solvation model and intersystem crossing. MOPAC2007 was followed by the release of MOPAC2009 in 2008 which presents many improved features
I’m still a young man
So I think very little of death
Who really does, ‘til its coming for them?
And I know with each breath I come one closer
But death is just a hook behind the door
Where I’ll leave my dirty clothes
They may dump my body in the sea
Spread my ashes miles wide,
It won’t matter,
All my parts will realign.
They rush to find each other
When they hear their Lover’s cry,
And death will be abandoned
When He comes back for His bride
Saints are never buried,
They are seeds planted
Who bring about a greater harvest when
They burst forth from
The earth that needed their fruits,
But it could never hope to make
Enough room for their roots.
(Ah Ah Ah Ah Oh)
Death is swallowed up,
(Ah Ah Ah Ah Oh)
It owns nothing in me,
(Ah Ah Ah Ah Oh)
Oh, death is swallowed up,
(Ah Ah Ah Ah Oh)
It owns nothing in me,
Oh, precious in the sight of the Lord
Is the death of His faithful ones.
Precious in the sight of the Lord
Is the death of His faithful ones,
Oh, death is swallowed up.
Oh, it was always you, it was always you.
Oh, it was always you, it was always you.
Oh, it was always you, it was always you.
Oh, it was always you, it was always you.
