CrystalMaker 是可視化晶體和分子結構的最有效方式。它的交互式設計讓您“see the wood for the trees”,並建立您對複雜材料的視覺理解。CrystalMaker超越了傳統的晶體學軟件,讓您可以使用可旋轉的動畫創建動態可視化。能量建模工具可讓您設計和放鬆新結構,預測其振動特性,並探索它們如何與其他材料相互作用。
探索奧妙的晶體世界
從金屬到沸石、苯環到蛋白質:CrystalMaker是最方便的一套分子建模工具,用以建構、視覺化、並了解晶體與分子結構。
快速建構晶體與分子模型
CrystalMaker內建的對稱性演算,助您跨越晶體學的艱澀,由程式自動生成所有的鍵結與多面體。
分子建構更為簡單:點擊滑鼠,自行加入原子與鍵結;使用程式中的"Relax"指令做熱力學演算,以最適化您建構的分子結構。
動畫化
CrystalMaker是第一個突破靜態結構框架、以動畫方式呈現結構變化的化學繪圖軟體。拖曳複數檔案進視窗、依時間軸排列它們的順序,即可存成影片。
Diamond 軟體的開發公司 Crystal Impact Gbr,成立於 1997年,其成立的目的是要開發優質的化學軟體;即使不是專家的使用者都能上手。Diamond 主要具有以下功能:晶體結構的求解、視覺化、材料資料庫和材料設計。全球有五十個國家以上的化學家和材料科學家(包含學術界和產業界)都在使用Diamond 來決定、視覺化和了解他們所在研究的化合物。

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。
基本功能
可用來預測氣相和液相條件下,分子和化學反應的許多性質,包括:分子的能量和結構;過渡態的能量和結構;振動頻率;紅外和拉曼光譜(包括預共振拉曼);熱化學性質;成鍵和化學反應能量;化學反應路徑;分子軌道;原子電荷;電多極矩;NMR 遮罩和磁化係數;自旋-自旋耦合常數;振動圓二色性強度;電子圓二色性強度;g張量和超精細光譜的其他張量;光性;振動-轉動耦合;非諧性的振動分析和振動-轉動耦合;電子親和能和電離勢;極化和超極化率(靜態的和含頻的);各向異性超精細耦合常數;靜電勢和電子密度。
基本演算法
可對任何一般收縮的gaussian 函數計算單電子和雙電子積分。這些基函數可以是笛卡爾高斯函數或純角動量函數,並且有多種基組存儲於程式中,可以通過名稱調用。積分可儲存在記憶體和外接記憶體上,或在用到時重新計算。對於確定類型的計算,計算的花費可以使用快速多極方法(FMM)和稀疏矩陣技術實現線性化。將原子軌道(AO)積分轉換成分子軌道基的計算,可用的方法有“in-core”(將AO 積分全部存在記憶體裏),“直接”(不需儲存積分),“半直接”(用磁片儲存部分積分),或“傳統”方法(把所有AO 積分儲存在磁片上)。使用密度擬合,加速純DFT計算的庫侖部分。數值求積分,計算DFT的XC能量及其微分。

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.
