最新版 ChemDraw / ChemOffice+ Cloud 全新推出
PerkinElmer Informatics is pleased to announce the release of ChemDraw and ChemOffice+ Cloud (formerly ChemOffice Professional) version 20.0, the Research Suite designed to help researchers bring their chemistry to life and quickly turn it into actionable chemical knowledge. Version 20.0 comes with several chemistry-improving capabilities as well as a brand new Cloud Application: ChemOffice+, designed to accelerate the Chemistry communication process. Here are some of the highlights of version 20.0:
New hotkeys: A new Molecule hotkey “Enter” is available to switch from a selected molecule to hotspot molecule editing. “k” now creates a sulfone group, “Shift+k” on primary carbon gives a tert-butyl group with 90° angles and on secondary carbons a wedged/hashed-wedged gem-dimethyl group. “Shift+o” creates a “OMe” group, and “Shift+e” a “CO2Me”. Upon 1st launch of ChemDraw 20.0, a comprehensive hotkey cheat sheet will be presented to the user.
Atom/Bond highlighting: Complementary to the version 19.0 Ring Fill coloring, atoms, labels and bonds can highlighted with a specific color to facilitate communication and audience focus.
3D Clean-up and Structure Perspective: A new 3D clean-up function will generate 3D confirmations of structures from 2D representations, to generate realistic 3D renderings in just a few clicks

CRYSTAL
CRYSTAL是研究固態晶體結構的計算軟體,可以用來研究分子、多聚物、表面和晶體的物理性質和化學性質。 例如:幾何結構、振動性質、電子態結構、磁學性質、介電性質、彈性等。自1988年第一個版本以來,CRYSTAL發布了92、95、98、03、06、09六個版本。 CRYSTAL程序使用Hartree-Fock、密度泛函或各種混合近似方法計算週期體系的電子態結構,所用的周期體系的Bloch函數用以原子為中心的高斯函數的線性組合展開。 程序還使用了屏蔽技術以充分利用實空間的局域化特性。 程序使用全電子基組或者價電子基組(有效核勢)進行限制性閉殼層,限制性開殼層,或者非限制性計算。 程序可以正確處理空間對稱性(230個空間群,80個平面群,99個柱形群,45個點群)。 點群對稱性與平移對稱性可以在分子體系上兼容。 CRYSTAL的輸入工具可以從三維晶體結構產生層狀結構(二維體系)或者團簇(零維體系),創建缺陷體系的超晶胞,還可以從一個單層結構(二維體系)創建納米管(一維體系)。

GAUSSIAN 是一個量子化學軟體,它是目前應用最廣泛的計算化學軟體之一,其代碼最初由理論化學家、1998年諾貝爾化學獎得主約翰·波普爵士編寫,其名稱來自於波普在軟體中所使用的高斯型基組。使用高斯型基組是波普為簡化計算過程縮短計算時間所引入的一項重要近似。Gaussian軟體的出現降低了量子化學計算的門檻,使得從頭計算方法可以廣泛使用,從而極大地推動了其在方法學上的進展。

New Modeling Capabilities
[REV C] NBO version 7 is supported. There are new options to the Population keyword: Pop=NPA7, Pop=NBO7, Pop=NBO7Read and Pop=NBO7Delete request Natural Population Analysis, full Natural Bond Orbital Analysis, full NBO with NBO input read from the input stream and NBO analysis of the effects of deletion of some interactions (respectively), using NBO7 via the external interface. In addition, Pop=NEDA is used to perform Natural Energy Decomposition Analysis. The analysis uses the same input information about fragments as counterpoise calculations. Deletions and optimizations with deletions now work with either NBO6 or NBO7.
[REV C] The RESP (restrained electrostatic potential) constraint can be included in computing potential-derived charges. For example, Pop=(MK,Resp=N) applies a weight of N x 10-6 Hartrees to the squared charges. Other electrostatic potential-derived charge schemes also accept this option (e.g., CHelp, HLY). N defaults to 2.
[REV C] Pop=SaveHirshfeld and Pop=SaveCM5 cause the specified charges to be saved as the MM charges to be used in a subsequent calculation.
[REV B] Static Raman intensities can be computed for excited states at the CIS and TD levels of theory. TD Freq=Raman computes the polarizability by numerical differentiation with respect to an electric field, so the cost of Freq=Raman for these methods is 7x that of the frequencies without Raman intensities.

HyperChem Release 8.0 incorporates even more powerful computational chemistry tools than ever before, as well as supporting multiple third-party applications. Its drawing and rendering capabilities and ease of use are standards for the industry.
In spite of the fact that HyperChem has extensive and elegant number crunching capabilities, it can’t be all things to all computational chemists. With Release 8, an effort to enable HyperChem as a universal component in computational chemistry begins. Release 8 includes an interface to six third-party packages that are in common use in computational chemistry. None of these packages includes a native graphical user interface. Each benefits from the capabilities of HyperChem and each set of users now has capabilities never imagined before. Now PC Gamess, WinGamess, PQS, Q-Chem, Gaussian, and Mopac2007 can all be transparently executed by HyperChem. Now each of these can act as a computational engine for HyperChem. They add to the large number of native omputational engines already in HyperChem, such as HyperGauss, HyperDFT, etc. The world just got easier.
